Question 5: For the angular position 8 = 60° of the crank OA, the gas pressure on the piston induces a compressive force P in the connecting rod along its centerline AB. If this force produces a moment of 720 N.m about the crank axis O, calculate P. [5 points - 1 point for writing the correct given, 2 points for the correct solution, 1 point for the correct final diagram with force P and the indicated moment, 1 point for the correct answer]
