If T [subscript L] and T [subscript R] are the tensions pulling at the left and right edges of the pulley (see Fig. 1), respectively, the net torque on the pulley is then T [subscript net] = (T [subscript L] T [subscript R])R, where "R" is the radius of the pulley. (It is assumed that positive torque corresponds to the counterclockwise direction.) While this analysis, which is typical of what is found in many introductory physics texts, is correct, it should raise several questions in the ... pulley, tension exists in both its ends. At the end towards the bucket, the tension is less than at the end towards the block. This then causes the block to pull itself down thereby raising the bucket.” FIGURE 1. Experiment set used by Sjoberg and Lie to probe stu-dent difﬁculties with forces. FIGURE 2. Experiment set used by Gunstone and White. The Pulleys . Problems involve two weights either side of a pulley. The heavier weight pulls on the lighter causing both to accelerate in one direction with a common acceleration. calculation of acceleration 'a' calculation of tension 'T' Example . A 3 kg mass and a 5 kg mass are connected over a pulley by a light inextensible string. If T [subscript L] and T [subscript R] are the tensions pulling at the left and right edges of the pulley (see Fig. 1), respectively, the net torque on the pulley is then T [subscript net] = (T [subscript L] T [subscript R])R, where "R" is the radius of the pulley. (It is assumed that positive torque corresponds to the counterclockwise direction.) While this analysis, which is typical of what is found in many introductory physics texts, is correct, it should raise several questions in the ... If I just assumed that this is how the string applies tension on the pulley, I was able to solve the problem, but I fail to understand why this is the case. PS:While this is technically a homework problem, I did this problem, but just had a doubt in drawing the free body diagram of the pulley.

Oct 10, 2009 · In the drawing, the weight of the block on the table is 422 N and that of the hanging block is 185 N. Ignoring all frictional effects and assuming the pulley to be massless, find (a) the acceleration of the two blocks and (b) the tension in the cord. I'm completely stumped on this one. I... Using a system of pulleys can be much more complex and provide a powerful mechanical advantage — greatly reducing the amount of force required to move an object. If one movable pulley is used (Figure 6), the amount of force required to raise the object attached to the movable pulley is cut in half. Jan 20, 2010 · A pulley is a simple machine consisting of a wheel turning on an axle. Pulleys are often used singly and in combinations to do work. If energy is conserved for a machine, then the work done by the machine must be equal to the work put into the machine: Work out = Work in

Firstly, the tension T1 and T2 is equal only when the pulley and the rope are massless. If the pulley has mass=> it will have considerable inertia momentum. Due to its angular acceleration, its torque will be different from 0 , which implies that T1 and T2 is not equal. Also, if the rope is not massless, the tension will also be different.Engineering Mechanics Dynamics Problems And Solutions Pdf Initial tension in the belt calculator uses Initial tension of the belt=(Tensions in the tight side of belt+Tensions in the slack side of belt+(2*Centrifugal tension of belt))/2 to calculate the Initial tension of the belt, Initial tension in the belt is the tension in the belt which is passing over the two pulleys i.e driver and follower when the pulleys are stationary is known as initial ...

An ideal pulley is a pulley in which the effects of friction and inertia of the pulley mass... on the pulley. Now, the only force acting on the pulley (whose line of action does not pass through the pulley's axis of rotation) is the tension in the cable. The torque associated with this force is the product of the tension,, and the perpendicular distance from the line of action of this force to the rotation axis, which is equal to the In other words work done (by the tension) at one end is positive and the same at the other end is negative but magnitude-wise both are same. Hence total work done by tension of an ideal thread/ rope is always zero. The statement applies to all the physical systems involving ideal string(s).
