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:

Two unequal weights are connected by a massless string which passes over a frictionless pulley.  If the pulley has no appreciable mass, the tension in the string is the same on both sides of the pulley; but if the pulley has mass, the tension will not be the same on both sides of the pulley.Group of answer choicesFalseTrue

The radius of a pulley is 182 mm. Find the circumference of the pulley. (This is the amount of rope that passes through the pulley as it rotates exactly once.)Round your answer to the nearest whole number. Do not type the units in the space below.

The figure below shows two blocks suspended by a single cord over a pulley. (Figure 1) The mass of block B is twice the mass of block A, while the mass of the pulley is equal to the mass of block A. The blocks are let free to move and the cord moves on the pulley without slipping or stretching. There is no friction in the pulley axle, and the cord's weight can be ignored.Figure1 of 1Part AWhich of the following statements correctly describes the system shown in the figure?Check all that apply.View Available Hint(s)for Part AThe acceleration of the blocks is zero.The net torque on the pulley is zero.The angular acceleration of the pulley is nonzero.

A 3.7-kg sphere is suspended by a cord that passes over a 1.3-kg pulley of radius 3.6 cm. The cord is attached to a spring whose force constant is k = 86 N/m as in the figure below. Assume the pulley is a solid disk.An apparatus is shown with a wall extending upward from the left end of a table and a pulley mounted above the right edge of the table. A horizontal spring labeled k has its left end attached to a horizontal cord, the other end of which is attached to the wall. The center line of the spring is aligned with the top of the pulley. The right end of the spring is attached to a second cord. This cord extends horizontally, over the pulley and 90° around it where it hangs downward. A sphere of mass m hangs from the end of the second cord.(a) If the sphere is released from rest with the spring unstretched, what distance does the sphere fall through before stopping? m(b) Find the speed of the sphere after it has fallen 25 cm. m/s

The figure provided shows two balls attached to a string moving in vertical circles. If both balls are of equal mass and speed, the tension in case A is ...
