Title

The Business of Footwear

Introduction

Donald Burrell a lover of footwear; May it be sandals, sneakers you name it. If it is footwear he loves it. Donald wishes to turn his love for footwear into a lifelong business. Donald is fully aware that his preferences in footwear will differ from the prospective customers that he wishes to serve. As such, Donald decides to conduct a research to identify various preferences in choices of footwear from his prospective customers.

From the research, Donald wishes to determine the primary choices of footwear

Method of Data collection

A questionnaire will be issued to fifty males and female collectively. This will be done over a period of two days. On day one, twenty five questionnaires were issued to males only. On day two, twenty five were issued to females only. On any given day, we will select the first five males between the ages of 16 – 25, ten every other fifth male till we get twenty five males. The same will be done for the females. Questionnaires issued gathers data on preferred type of footwear, materials used for footwear and colour, shoe size, age group and sex of participant, price of shoes.

Analysis (for Males)

The modal group for preferred footwear was sneakers, the modal preference for the material for the footwear was leather, and the modal colour black was price while the price range was $3000 - $4000.

The overall percentage of those who preferred sandals was 8% while those from the 21-25 age group measured 11%. The overall percentage of those that preferred sneakers was 60 while from the 21- 25 age group it was 50%. The overall percentage of those who wanted dress shoe was 32% while those who preferred it from the 21 – 25 age groups was 39%. Overall, the number of participants from the age group 21 -25 accounted for 72% of all participants.

Discussion

Given that the probability of someone from the age group 21 – 25 buying a shoe is 72%; which is very high, and that the percentages for the age group 21 – 25 closely resembles the percentages for the overall data; within similar categories, it is okay to make shoes using the overall data or the data from the 21 -25 data set.

While Donald focuses on preferences, he may make limited amounts of other types of footwear from various materials and in various colours, this for the sake of variety.

Conclusion

Donald should focus primarily on sneakers and secondarily on dress shoe; of either leather or suede, black or white not costing more than $4000.

PROJECT IDEA 2

Title

Introduction

Alex Messam knows the type of lifestyle he wants to live; the area and house he want to live in, the car he wants to drive, how often he wants to party and the parties he wishes to go to, the type of food they wish to eat and vacation they wish to enjoy. What he may not be aware of is the profession he needs to successfully sustain such a lifestyle.

Also currently, Alex is not performing at the level he needs to find himself in the professions he needs to sustain his particular lifestyle.

So in this project Alex will record his family’s expenditure over a 4 week period, and then compare it to their expected monthly expenditure based on his lifestyle.

The aim of this project is to

1. Sensitize students to the cost of living2. How to prioritize spending3. Identify the professions that will suit their lifestyles best, and inadvertently show then the

amount of effort and time they need to invest in order to achieve

Method of Data collection

1. Each day over a four week period, the student will record his daily expense in the table for daily expenditure.

2. After the four week period has ended, the student will visit any property website to determine the type of house and community they wish to live in, and retrieve a quote for that house.

3. They will use an online mortgage calculator to determine monthly payments. And record it in the lifestyle expenditure table.

4. Using the internet they will continue to fill out the lifestyle expenditure table.

Growing Tomatoes

Introduction

Donald Burrell is set on farming organic tomatoes for the rest of his life. His father was a major producer of tomato also, and had a massive farm where his (the father’s) employees tilled and water the soil around each plant daily. Donald is interested in owning a farm, not in doing so much work, so after some research, he saw where he could grow them using the hydroponic method.

What he did not know was how long the hydroponic method would take to produce adult plants; that would intern bear fruit. This was important to him as he knew that the longer it took to get adult plants the lower the amount of crop he would yield in a year and the lower his revenue would be.

He wishes to conduct an experiment to determine

1. The growth rate of tomatoes by organic means in water as against soil, and, 2. Hence, which method is better

Method of Data collection

1. Plant three tomato plants in soil2. Label plants A and B3. Repeat steps 1 and 2, for method of hydroponic using D and E4. Record how long it took each plant to germinate5. After germination record the height of the plant every morning over a 3 weeks period6. Plot a graph of day vs height for each plant 7. Compare growth rate

Analysis

The growth rate of plants A and B were 0.4114 cm/day and 0.2607 cm/day respectively. This is a difference of 0.1507 cm/day. While the growth rate of plants C and D are 0.7141 cm/day and 0.7343 cm/day. A difference of only 0.0202 cm/day compared to the difference in plants A and B. On day 10, plant A and B ad an height of 4.3 and 3.2 cm respectively, an average height of 3.75 cm. While Plants C (7.0 cm) and D (7.2 cm) averaged a height of 7.1

Discussion

Given that the average height of plants A and B (grown in soil) was 3.75 cm on day 10, while plants C and D (grown in hydroponic solution) was 7.1. This suggests that the hydroponic solution grows food faster. This is supported by the growth rate of plants C and D which is at least 0.3 cm/day faster than plants A and B. The reason for this may be because the hydroponic solution has all that is needed for the plant to

grow, while with the plants grown in soil, they will have to search for nutrients at all times for the plant grow, this makes the time for the plant to grow longer and the rate slower.

Conclusion

Tomato plants grown in hydroponic solution grows faster.

Economics of Painting

Introduction

It is time for your school to receive a face lift, and your principal consults you on the ways you wish to see this done, it was decided that painting the schools Administrative block should be first and foremost. He then leaves the planning of the project to you. As such, you consulted a painter who said the following to you

1. The building requires two (2) coats of paint.2. Each 10-meters squared of the building requires 5-litres of paint per coat3. He can cover 40-meters squared per hour painting and only paints 4 hours daily as any longer is

detrimental to his health4. And his daily rate of painting is $2750

With this you, have split the project with a person responsible for each of the four walls. Each person will determine

1. the area of the building that needs to be painted

Option A (two group members will do this option)2. the amount of paint required for the specific colour of paint and its cost

Option B (another two will do this option)3. the cost of labour

The group (if group is four members) or the fifth member will then determine

4. the total cost of the project

Method of Data collection

1. Stand 390 cm from the base of the building2. Using a clinometers app, measure the angle of elevation to the top of the building3. Calculate the height of the building 4. Repeat steps 1 – 3 for 500 cm5. Using a tape, measure the width of the surface of the building6. Calculate the total surface area

7. Calculate the area of all windows and doors and subtract from the total surface area to determine the surface area that needs to be painted.

Presentation of Data

Calculation for height and Area of wall

The height of the side A, standing 390cm from the base of the building = 390 cm∗tan(53.21)=521.50 cm

The height of the side A, standing 500cm from the base of the building = 500 cm∗tan(46.67)=530.00 cm

Average calculated height = 530+521.5

2=525.75cm

Height of the wall (average height + height of person measuring angle of elevation) =525.75 cm+175.00 cm=700cm

This is the same as 7m

Width of wall is12m

Therefore Height of wall =7m∗12m=84m2

Area of Windows and doors

Area of Window (Aw¿

Aw=1.82m∗3.65m=6.643m2

Area of door (A¿¿ d)¿

Ad=4.14m∗1.35m=5.589m2

Area of door window (A¿¿ dw)¿

Adw=0.9m∗2.6m=2.34m2

Prices

The price of labour is $2750 per day

The price of paint is $2400 per tin of paint, there are 3.78 l in each tin of paint

Analysis

There are three windows, two door windows and one door, all these areas of the wall labeled side A does not need painting. So the Area of the wall that does not need painting is An. Now

An=Ad+2 Adw+3 Aw=30.198m2

So the total Area that needs paint is At=height of wall−An=84m2+30.198m2=53.802m2

Option A

Given that the ratio of area to paint needed is 10m2:5 l

For an area of 53.802m2 we would need 53.802m2∗5 l

10m2=26.541l

Since there are 3.78 l of paint per tin we would need 26.541l

3.78 ltin

=7.02 tins∨8tins

Given that the cost per tin is $2400 the total cost for paint is ¿number of tins of paints∗cost per paint=8∗$2400=$19200

Given that there will be two coats of paint applied, the value will be $38,400

Option B

Given that the area of the wall that needs to be painted is 53.802m2 and the painters work rate per

hour is 40 m2

hr , then total time needed for the painter to paint the given area is

¿ 53.802m2

40 m2

hr

=1.327hr

or 1hr∧20mins. Given that the time will be doubled since a second coat of paint will be added, the actual time that will be taken is 2hrs∧40mins , which is below the 4hrstipulation given by the painter, he will complete the job within one day and his cost for the job on Side A will be $2750

Discussion

The total area of the building that needed painting is 107.604m2 given that the area that needs paint will get two coats of paint, the time needed for the wall to be painted is 2hrs∧40mins, since the paint will be applied twice.

Conclusion

The cost for the project is $41,150and will take 2hrs∧40minsto complete.

Building a Bench

Introduction

The school has just painted the classrooms of the 5th-form block. The school wants to keep the classes as clean as possible for as long a time as possible. They determine that in order to do this, they must keep the amount of students who stays inside the classroom as low as possible. This means that most of the students will be outside as a result. As such the school decides place benches (under trees or under a gazebo). As a student of building technology, your teacher asked you to design benches made of (wood and metal or concrete). He gave the following constrains,

1. The supporting arch of the base must be a semicircle2. The surfaces of the bench must be flat3. If concrete, the width of each leg must be 7 cm4. The ratio of water to dry components is 1:15. The ratio of the dry components cement, sand and aggregate is 1:2:3 respectively

With these, you are to

1. design a bench model with a scale of 1 cm on drawing: 10 cm in actuality

2. determine the amount of materials needed to make the bench

Method of Data collection

1. Get a standard sized chair used by students in a classroom2. Measure and record the distance from ground to seat3. Measure and record distance from seat to the top of the back support of the seat.4. Measure and record the length and width of the seat.5. Use these measurements to design a bench to seat three (3) persons.

Presentation of Data

Analysis

Let the volume of one bench side vbs=total surfacearea of bench side(A t)∗widthof benchside

Now At=Areaof A ( Aa )+Area of B ( Ab )−Areaof C ( Ac)−Areaof D(Ad)

Aa=L∗W=1cm∗20cm=20cm2

Ab=L∗W=3.6cm∗4cm=14.4 cm2

Ac=12π r2=

12∗22

7∗(1cm)2=11

7cm2≈1.6cm2

Ad=L∗W=2cm∗2.28cm=4.56 cm2

Therefore At=28.24 cm2

And V bs=28.24 cm2∗4 cm=112.96cm3 and since there are two sides the volume of the two sides is

225.92cm3.

Now, the volume of the seat V ℶ=L∗W∗H=12cm∗4 cm∗0.7cm=33.6 cm3

Hence the total volume of one bench is V b where V b=2V bs+V ℶ=259.52cm3

But recall that these sets of calculations were done using the scaled values, so we must now find the actual volume.

From the introduction, we see that the ratio of scaled drawing to actual model is 1 cm: 10 cm. Therefore, for every 1cm3 scaled we have1000cm3∨1m3. So the ratio of scaled volume to actual volume is1cm3:1m3, giving us an actual volume of 259.52m3 , but we will use a volume of 260m3 .

Now we will calculate the material needed by measurement of 12 l construction buckets.

Given that the ratio of wet and dry components is 1:1, then the volume of the dry parts

¿ ratioof dry part∑ of ratios

∗total volume=12∗260m3=130m3 .

So the volume of cement needed¿ratioof cement∑ of ratios

∗total volume=16∗130m3=21.66¿≈22m3.

One bucket holds 12 l ,so we will need 2212

=1 56buckets of cement (recall1m3=1l)

The number of buckets of sand is ¿2∗1 56=3 23 buckets of sand, since ratio of cement to sand is 1:2.

And similarly, the number of buckets of aggregate needed =3∗1 56=5 1

Discussion/conclusion

A suitable design for a bench is shown in the presentation of Data above. Also, for every bench it will

require, 11buckets of water ,1 56buckets of cement ,3 2

3buckets of sand∧5 1

2buckets of aggregate .
