The 100-kg crate is hoisted by the motor M. If the velocity of the crate increases uniformly from 1.5 m/s to 4.5 m/s in 5 s, determine the tension developed in the cable during the motion

The collar has a mass of 28-kg and slides along the smooth rod. Two springs are attached to it and the ends of the rod as shown. S kA kB: 12 0.25 m Each spring has an uncompressed length of I1=2-m and l2=3-m and stiffnesses k1=51-N/m and k2=176-N/m respectively. Determine the velocity that must be subjected to the collar to generate a compression of 0.7 m

Determine the constant force “f” w/c must be applied to the cord in order to cause the 39lb block to have a speed of 22 ft/a when it has been displaced 0.5 ft upward starting from the rest.

The collar with mass of 0.7 kg is released from rest at position A and travels down the smooth circular rod in the vertical plane. If the velocity of the collar at Point C is 3.3 m, determine the tangential component of acceleration of the collar (in m) at Point C. The spring has a stiffness of k = 140 N and an unstretched length of 0.5 meters. Consider R = 1.7 meters, 0 = 33°, and g =10 A m R/2 D В R

The 15-kg block is subjected to the force shown. Determine its velocity at s= 4m if v= 6 m/s at s=0. Motion occurs to the right. F= (5.1 s)N

The 750-mm-long spring is compressed by the plate P, which can slide freely on the 600- mm-long vertical bars. The 55.6-kg block is given a velocity of v = 5 m/s when it is x = 2 m above the plate. Determine how far the plate travels down when the block stops momentarily after hitting it. Neglect the mass of the plate. v = 5 m/s P k = 25 kN/m- A h = 2m 600 mm
