- A rotating wheel has a radius of 2 feet and 6 inches. A point in the rim of the wheel moves 30 feet in 2 sec. Find the angular velocity of the wheel.arrow_forwardQ8) You are designing a system for moving aluminum cylinders from the ground to a loading dock. You use a sturdy wooden ramp that is 2.00 m long and inclined at 37.0 degrees above the horizontal. Each cylinder is fitted with a light, frictionless yoke through its center, and a light (but strong) rope is attached to the yoke. Each cylinder is uniform and has mass 420 kg and radius 0.300 m. The cylinders are pulled up the ramp by applying a constant force F to the free end of the rope. F* is parallel to the surface of the ramp and exerts no torque on the cylinder. The coefficient of static friction between the ramp surface and the cylinder is 0.120. a) What is the largest magnitude F° can have so that the cylinder still rolls without slipping as it moves up the ramp? b) If the cylinder starts from rest at the bottom of the ramp and rolls without slipping as it moves up the ramp, what is the shortest time it can take the cylinder to reach the top of the ramp?arrow_forwardLearning Goal: To be able to analyze the equilibrium of systems subjected to frictional forces at belts and surfaces. When engineers design belt drives and band brakes, they engineer them to withstand the frictional forces that develop between the belts or bands and their contacting surfaces. These frictional forces lead to tensions on each side of the contacting surfaces that are unequal; the segment aligning with the motion of the belt or band has a greater tension Figure B 0 B HA 1 of 3 PC > Part B Blocks A and B have a masses of 160 kg and 290 kg, respectively. (Figure 2) The coefficient of static friction between A and B and between B and C is 0.290. The coefficient of static friction between the rope and peg E is 0.590. Pulley D rotates freely, and P = 16.0 N. If 0 = 60.0 degrees, what is the smallest magnitude, T, of tension, T, that causes block B to move?
