A plumber pulls out a 0.400 m long Wrench and places it around a bolt that has a diameter of 0.0200m. We will treat the bolt as a solid disk (I=%M R2) with a mass of 0.450kg. The plumber applies a constant force of 10.0N at an angle of 750 on the end of the wrench for one quarter turn. A. What was the torque applied to the bolt? B. The force of friction on the bolt is measured to be 185N at a tangent to the edge of the bolt. What is the net torque acting on the bolt? C. Calculate the angular acceleration of the bolt during the quarter turn. D. Assuming the bolt started from rest, what is the angular velocity of the bolt after one quarter turn? A window washer with a mass of 60.0kg starts from the left side of a 125kg platform that is 8.00m long. The platform is uniform so that the center of mass is in the middle of the platform. A. The rope on the right is worn out and can only apply 1000.0N of force. How far can the man walk before the rope breaks? B. What would be the tension on the left rope right before the right rope broke
