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...

The bell crank fits over a 100-mm-diameter shaft which is fixed and cannot rotate. The horizontal force T is applied to maintain equilibrium of the crank under the action of the vertical force P 100 N. Determine the maximum and minimum values which T may have without causing the crank to rotate in either direction. The coefficient of static frietion between the shaft and the bearing surface of the crank is 0.20.

A solid uniform cylinder of mass M and radius R is at rest in
the center on a flat slab of mass m and thickness d, which in turn
rests on a horizontal, frictionless table, as shown in the figure at
right below. A horizontal force of magnitude F is applied to the
slab, acting through the center of the slab, causing it to
accelerate to the right. The cylinder rolls without slipping on the
slab. (The direction of F...

The figure shows a uniform disk that can rotate around its center like a merry-go-round. The disk has a radius of 2.0 cm and a mass of 18 grams and is initially at rest. Starting at time t = 0, two forces are to be applied tangentially to the rim as indicated, so that at time t = 1.2 s the disk has an angular velocity of 300 rad/s counterclockwise. Force F1 has a magnitude of 0.101 N. What is...
