Spring: If the coefficient of friction is 0.37,how far will the block travel up the slope?
A 37kg object is placed onto a coil spring which has been compressed 43mm. The force used to compress the spring was 35KN.The spring and the object are on the same incline plane angled at 21deg from the horizontal. If the coefficient of friction is 0.37,how far will the block travel up the slope?
A rod 2.75m long, 30mm in diameter is put under stress of tension of 104 MPa. If "E" is 210 Gpa, find the a) Load on the rod b) Amount of tension c) Work done in pulling the rod
(see attachments) FYI: In this posting I will write A (sub x) as Ax. I will Write Sigma (or sum) as {E} Find the force exerted by pin A on the structure. I know that i first make the free body diagram. 1. Try the entire frame: IN second attachment, image on left. Problem...this is 4 unknowns, but we're on ...continues
