Q5.) Wedge B is positioned above wedge A as shown. Each wedge has a mass of 12 kg. A linear elastic spring attached to wedge A has a spring constant of 3 kN/m and is currently compressed 0.06 meters from its unstretched length. The coefficient of static friction between the two wedges is 0.5 and the coefficient of static friction between wedge A and the ground is 0.35. A force of P is applied to the corner of wedge B at an angle 30°. Determine the minimum applied force that would cause motion to occur and specify how the system will move. k = 3 kN/m A 20° B 30°
