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 96.0% of its original uncompressed length l= 3.00 m, and the spring constant is given as k = 1750 N/m. The coefficient of static friction at all contacting surfaces is ls = 0.150. The mass of the crate is m = 23.0 kg . The angle is 0 = 13.0°. Neglect the mass of the wedge. Assume the crate only moves in the y direction and that wedge A cannot move. (Figure 1) Figure 1 of 1 В
