1. A cylinder with outer radius, router is 1.8 meters is supported by a fixed axel as shown below. The radius of the axel, raxel is 0.20 meters. An external applied force, Fa, of 80 N is applied tangentially to the outer cylinder as shown causing the cylinder to rotate about the axel. The torque at the cylinder due to friction at the axel is 12 N-M. The kinetic frictional force direction is shown below. The entire configuration has a rotational inertia, I, of 900 kg-m² raxel router a. What is the torque created by the 80 N force? b. What is the net torque on the nested cylinders? c. What is the direction of rotation of the nested cylinders? d. What is the magnitude of the frictional force? e. What is the rotational acceleration? f. What is the rotational speed after 15.0 sec if the cylinders start from rest? g. Through what angular displacement does the cylinder move during this time? h. What is the kinetic energy at this point in time? Some potentially useful equations: T = la w(t) = wi + at 1 O(t) = wi + w;t +,at² 2 1 MV?; KE = KE =
