A sadistic carnival operator has designed a ride based on a fourbar linkage, shown in Figure 7.141. The passenger sits at point P while the crank rotates at a constant 40rpm. The thickness of all links is 25mm, and all links are made of aluminum. Assume that the rider is a point mass of 100kg located at point P. The distance between ground pins is 1200mm. Calculate and plot the forces in the x and y direction at the crank pivot, and the driving torque required to operate the ride. Do not ignore gravity.
