A force of 200N is applied to the rim of a pulley wheel of diameter 200mm. The torque is:a.10Nmb.2Nmc.20Nmd.20kNm

What is the net torque about the axle on the pulley in? Express your answer in newton-meters.

A double pulley is free to rotate about its axis through its center. The radii of the two pulleys are   and  . Two cords are wrapped in opposite directions on the pulleys and are attached to masses. As a result, the two tension forces acting on the pulley are equal and acting downwards as shown in the image below so that  .A diagram shows two concentric circles around a central point. The smaller circle has a radius of R. The larger circle has a radius of two R. From the left side of the smaller circle an arrow labeled F sub one points straight down. From the right side of the larger circle an arrow of the same length, labeled F sub two, points straight down.When released from rest, what will be the direction of the angular acceleration?Choose 1 answer:Choose 1 answer:

By applying a force of 50 N, a pulley system can lift a box with a mass of 20 kg.  What is the mechanical advantage of the pulley system?
