For the mechanism in the posture shown, the pin at the center of the wheel is sliding in the slot in link 2, and wheel 3 is rolling without slipping on the ground link. The constant angular velocity of input link 2 is ω2 =1.50kˆ rad/s, the angular acceleration of the wheel is α3 = −62.354 kˆ rad/s2, and the acceleration of the center of mass of the wheel is AG3 = 3.117 7 ˆi m/s2. The masses and mass moments of inertia of link 2 and the wheel are m2 = 15 kg, m3 = 25 kg, IG2 = 0.105 N · m ·s2, and IG3 = 0.016 N · m · s2, respectively. Gravity acts in the negative y direction. The force acting at point C is FC = 75ˆi N, and there is a torque, T12, acting on link 2 at the crankshaft, O2. Determine the torque, T12, and the minimum coefficient of friction between the wheel and the ground.
