2. The figure shows a jam cleat designed for a sailboat where the large friction forces developed by the cams prevent the rope from slipping. Determine the force R supported by each cam bearing from the 900-N rope tension. The coefficient of static friction between the rope and the cams is 0.8. Hint: FBD of one cam only. The line of action of R passes through the point directly above the center of the 80-mm circular cam profile and the center of the cam mounting pin. Ans: R = 1885 N 80 mm. 20 mm 900 N
