Wedges

Learning Goal:

To use the equations of equilibrium to analyze a system containing a wedge and to determine the necessary applied force to introduce motion into the system.

The crate shown is held against wedge B by a spring. The spring is 94.5% of its original uncompressed length l=2.75m, and the spring constant is given as k=1650N/m. The coefficient of static friction at all contacting surfaces is ?s=0.130. The mass of the crate is m=26.0kg. The angle is?=13.0?. Neglect the mass of the wedge. Assume the crate only moves in the y direction and that wedge A cannot 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.
