Unformatted text preview: The shaft has total moment of inertia I zz = mR 2 /2 = 0.18 kg m 2 , and product of inertia I zy = 2R 2 m/3 π = 0.0764kg m 2 around x,y and z axes through point O. A constant torque (not pictured) of M z =0.20Nm k is applied to the shaft starting at time t=0. What is the angular speed ω after 4 seconds? What are the moments M x and M y on the shaft at time t=4 seconds? What are the forces Q x and Q y acting on the shaft at point Q at that time? Ignore gravity. 4] The uniform cylinder of radius R and mass m rolls to the right. It has a point mass (also m) attached as indicated on the rim. At the pictured instant the point mass is at the position indicated and the cylinder rolls with ω =1. Find the angular acceleration α of the cylinder....
