ENT 151 Statics PPK MekatronikCOURSE OUTCOME (CO)

• Course Outcome (CO):

• CO1: Able to use basic concepts of mechanics and vector mechanics to solve static equilibrium problems.

• CO2: Able to use and explain the concepts of force equilibrium and statically determinate structure.

• CO3: Able to use and explain the relation between the concepts of static’s resultant force and the applications of frictions.

• CO4: Able to explain and compute the forces in structures. e.g. Truss, frames and machines.

Assignment 1

• Do the following questions:

2.5, 2.18, 2.25, 2.34, 2.43, 2.54, 2.61, 2.71

(All the questions are taken from Vector Mechanics for Engineers Statics, by Beer and Johnston, Seventh Edition in SI Units)

• Please submit the assignment to Mr. Azizul on Monday, 21st January 2007 at the end of the class.

• Late submission will be penalized. Failure to submit the assignment without any valid and concrete explanation will lead to no point been awarded.

• Please try as much as possible do it by yourself. If still having difficulties, please discuss with your fellow course mates. Feel free to ask guidance from any of the lecturers, but please do not expect us to solve the problems for you.

• The final answers for all the questions is available at the end of the textbook. Please kindly notice that we would rather look at your attempt and problem solving skills instead of the final answer. Good luck!
