A 50kg uniform disk with a radius of 180mm is rolling down a 20 degree incline. This wheel has a radius of gyration about its center of gravity (which is at the center of the drum) of 120mm. Assuming its is rolling without slipping, what is the acceleration of the center of gravity and the minimum value of the coefficient of static friction for this situation?

A uniform drawbridge must be held at a 37° angle abovethe horizontal to allow ships to pass underneath. The drawbridge weighs45,000 N and is 14.0 m long. A cable is connected 3.5 m from thehinge where the bridge pivots (measured along the bridge) and pullshorizontally on the bridge to hold it in place. What is the angular speed of the drawbridge as it becomes horizontal?
A way to test the tensile strength of a wire is to place a mass at the end of it and spin the mass with uniform circular motion. The speed at which the wire breaks is a measure of its strength. The maximum frequency of rotation before a certain wire breaks is 35.5 Hz. The wire is 50.5 cm long and has a mass of 0.656 kg. (a) Determine the speed with which the mass moves. (b) Calculate the centripetal force acting on the wire
