Question

VODIL 1 0 PUN ) The "w" is a distributed load. Its magnitude is the last letter of your netID (units: lb/ft). Your full netID: and the last number of your netID is: _ The last number will be w. (Example: Pedro's ID is xd5613, he would use w = 3 lb/ft, you must use the last number of your own ID) Determine: a) Equivalent Resultant Force : b) Equivalent Resultant location, measured from A: 3 ft

Answer 1

– – – Let of & the , 2 be the ude , uul resultant forces respectively. F = w x 3 = 30 lb F2 = 1.W.3 = 1.5w 16. distance of F from A = 2 = 1.5' distance of 5 from A = 3+ }(3) = 4' orce Let the equivalent Resultant force be 'FR 8. I is acting at a distance of x' from point A.

FR = F + F – 30+l.su IF TR = 4.50. lbs to Equivalent Resultant - to w los force. sc? Calculation of equivalent resultant location (measured from A). Taking moments about point A, we get FR x x = F x 1.5 + F₂ x4 * (4.5w) x x = 3w x 105 + losw x4 * (4.5w)x sc = 10.50 o = 2.33
