Is there any difference between the free body diagram of fixed pulley and movable pulley? Not particularly. The main thing is that you can assume the fixed pulley isn't accelerating, so all forces on it must sum to zero. A movable pulley may or may not be accelerating. is it true that fixed pulley has T1 and T2, but movable has T2 on both sides ...

Also, let the magnitude of accelerations be “a”. Static pulley system. Free body diagram of body of mass 10 kg.

From the perspective of a free-body diagram the compound pulley system could be replaced by tying two ropes to the load and pulling up on each with a force equal to the effort. The disadvantages of pulleys, in contrast to machines that use rigid objects to transfer force, are slipping and stretching.

free-body-diagrams. T From the above discussions, we have the three equations: This is less than that in case 1 as we predicted. 9. Atwood's machine. Atwood's machine involves one pulley, and two objects connected by a string that passes over the pulley. In general, the two objects have different masses. a a. 10. Re-analyzing the Atwood's ...

A complete free-body diagram of the pulley, shown in Figure 11.3 (a), reflects that fact that the center-of-mass of the pulley remains at rest, so the net force must be zero. There is still a non-zero net torque, about an axis through the center of the pulley and perpendicular to the page,

Free body diagrams. The mechanical advantage of a pulley system can be analysed using free body diagrams which balance the tension force in the rope with the force of gravity on the load. In an ideal system, the massless and frictionless pulleys do not dissipate energy and allow for a change of direction of a rope that does not stretch or wear.
