Shear&forces&occurred&at&the&bo/om&of&the&structure&causing&the&sides&to&go&on&opposite&ways.&&

The&structure&can&be&strengthened&by&rearranging&the&pine&direc9on&horizontally.&I&guess&by&that,&the&beam&can&take&more&load&rather&than&small&pieces&put&ver9cally.&&

Group&1&

The&plywood&started&to&buckle&from&the&beam&itself&and&experienced&depression.&With&a&deflec9on&point&of&50mm,&it&is&considered&as&a&quite&strong&beam&as&it&could&take&up&to&250kg.&&

The&bo/om&part&of&this&beam&experienced&tension&while&compression&at&the&top.&Hence&I&guess&this&beam&can&be&strengthened&by&puJng&the&extra&plywood&at&the&top&instead&of&puJng&it&across&the&side&of&the&beam&

Group&2&

This&is&the&beam&that&my&group&made.&It&has&60mm&deflec9on&and&it&could&take&weight&up&to&590kg.&&

Comparing&to&the&first&beam,&we&put&the&pine&horizontally&hence&it&might&be&the&reason&why&it&was&stronger.&&

The&plywood&experienced&shear&forces,&hence&I&think&it&could&be&be/er&if&we&put&the&plywood&at&the&top&of&the&pine&instead&of&at&the&side.&&&

This&group&was&inspired&by&the&I&beam.&It&is&very&interes9ng&how&much&this&I&wood&beam&could&take&a&weight&of&330kg.&I&thought&that&it&should&be&stronger&than&any&other&beams.&&

It&is&also&interes9ng&that&the&space&between&the&plywood&and&the&pine&becomes&larger&as&more&weight&is&inserted.&&

The&beam&experienced&bucking&due&to&compression.&Hence&I&think&the&beam&could&be&strengthened&by&puJng&more&support&at&the&top&of&the&beam&because&that&is&where&the&weight&is&inserted.&&
