5. A connecting rod of length /= 12 has a mass m3= 0.02. Its mass moment of inertia is 0.62. Its CG is located 0.4/ from the crank pin, point A. A crank of length r = 3.5 has a mass m₂ = 0.06. Its mass moment of inertia about its pivot is 0.3. Its CG is at 0.3r from the main pin, O₂. The piston mass=0.012. The linkage is running at a constant 2000rpm and crank position is 45°. a. Exactly balance the crank and recalculate the inertia force b. Overbalance the crank with approximately two-thirds of the mass at the wrist pin placed at radius -r on the crank and recalculate the inertia force. c. Compare these results to those for the unbalanced crank.
