y - y = 4.5 – x h ft k lb/ft B I ft The 8-lb collar has a speed of 9 ft. s at A. The attached spring has an unstretched length of 2 ft and a stiffness of k = 15lb. ft-1. If the collar moves over the smooth rod, determine its speed when it reaches point B. The height of A is h = 6 ft and B is at l = 4ft from the vertical of A www
The motor winds in the cable with a constant acceleration, such that the 20-kg crate moves a distance s = 6 m in 3 s, starting from rest. Determine acceleration. what is the normal force (N) at point A. Determine the tension developed in the cable. The coefficient of kinetic friction between the crate and the plane is u= 0.3.
The 50-1b block rests on the smooth surface. A force F = (40+s) Ib, which s isin ft, acts on the block in the direction shown. If the spring is originally unstretched (s = 0) and the block is at rest, determine the power developed by the force the instant theblock has moved s = 1.5 ft.F30°k = 20 lb/ft
The block has a mass of 40 kg and rests on the surface of the cart having a mass of 78 kg If the spring which is attached to the cart and not the block is compressed 0.2 m and the system is released from rest, determine the speed of the block with respect to the cart after the spring becomes undeformed. Neglect the mass of the wheels and the spring in the calculation. Also neglect friction. Take k = 310 N/m
