Question

QUESTION 2 Two ropes, with tensions T1- 5 N and T2 - 2.5 N, pull on a pulley as shown in the figure T1 T. 2 The pulley is a uniformly dense cylinder with a radius of 5 cm and a mass of 2 kg. The pulley rotates around a frictionless axle that passes through its center. The pulley is initially at rest, but after the tensions are applied begins to rotate. What is the net work (in J) done on the pulley by the tensions during the first 5 s that the tensions are applied?

    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...
