determine the normal force nc that the crate exerts on the wedge when the system is at rest.
The crate shown is held against wedge B by a spring. The spring is 96.0% of its original uncompressed length l=3.00 m, and the spring constant is given as k=1450 N/m. The coefficient of static friction at all contacting surfaces is =0.150. The mass of the crate is m=28.0 kg. The angle is =12.0deg. Neglect the mass of the wedge. Assume the crate only moves in the y-direction and that wedge A can not move. Determine the normal force Nc that the crate exerts on the wedge when the system is at rest. Determine the magnitude of the smallest horizontal force P that is necessary to begin moving the crate upward.
