Creator: Nicholas Giordano | Science - 2012-01-01 (We omit the force of gravity on the pulley because it is balanced by the force from the pulley's support, and neither of these forces ... To find the torque on the pulley, we first note that the tension in the rope will make the pulley rotate clockwise.
IIT Physics Topic Wise Solved Questions
Creator: Tmh | A light inextensible string that goes over a smooth fixed pulley as shown in the figure connects two blocks of masses 0.36 kg and 0.72 kg. Taking g = 10 m/s2, find the work done (in joules) by the string on the block of mass 0.36 kg during the ...

Questions and exercises on Stewart's Lessons in elementary physics
Creator: George Anthony Hill, Balfour Stewart | 1880 One simple principle will explain the mechanical advantage of any system of Pulleys, however complex, namely, the principle of the tension of a cord, given in the solution of 169. The single movable Pulley is shown in Fig. 13. There is only ...
