The doorstop experiences trapezoidal pressure distribution in the friction pad, as shown in the figure. a = 8 in, b = 4 in, c = 3.25in, w₁ = 1.5 in, and w₂ W2 = 1 in. f = 0.2. The floor is moving to the right relative to the friction pad. Compute the magnitude of the normal forces and friction forces. . . Draw the free body diagram. Be sure to include necessary force components and their locations. What is the actuation force necessary to achieve static equilibrium? Find the reaction forces at the hinge.
