Question 2 (8 marks) Applied force A vertical pulley, of radius 0.4 meter, can rotate about a horizontal axle (axle has friction) that goes through its center. The rotational inertia of the pulley about this axle is 16 x 10 kg.m. The torque due to friction in the axle is constant, with magnitude 0.8 Nm. A vertical force, of constant magnitude 11.0 N, is continuously applied tangentially to the rim of the pulley as shown above. The pulley is initially...
