Question

2) The system shown is in equilibrium. It is known that the moment at E is 1200lb-ft counterclockwise and that the weight of block (J) on the incline is 1000lb. Find: a) WA and WB, b) tension coming off the pulleys at C, d) tension DG, e) force in bar GH and tension (T) attached to block J, f) normal force on the block, g) stiffness of spring 5, h) forces in each of the springs. Springs 1, 2, 3 and 4 have stiffness's of 40001b/ft, 3000lb/ft, 2807.5lb/ft, and 1422.5lb/ft, respectively. Springs 1 and 5 are observed to deform 0.4' and 0.5', respectively. 6400lb WA 30 0

Explanation / Answer

I have solved most of this but I have been given the oppertunity to get extra credit if it's 100% correct so I would greatly appreciate some help to ensure I didn't veer away from the correct answers
