Pulleys (and in particular the block & tackle) are an example of something often referred to as a simple machine. This is because we can use such a device to lift a heavy weight with a force less than the weight itself.
20 Ιουλ 2022 · The forces on the moving pulley P are the gravitational force \(m_{P} \overrightarrow{\mathbf{g}}=\overrightarrow{\mathbf{0}}\) (the pulley is assumed massless); string B pulls down on the pulley on each side with a force, \(\overrightarrow{\mathbf{T}}_{B, P}\) which has magnitude \(T_{B}\).

In this lesson we learn about dynamics problems that involve several masses that are connected and accelerating together. Using the pulley system illustrated to the right below as an example, the basic method for solving problems involving a system of masses is discussed.
Both pulleys are “light” in the sense that their rotational inertias are small and their rotation contributes negligibly to the kinetic energy of the system. The rims of the pulleys are rough, and the ropes do not slip on the pulleys. The gravitational acceleration is g g.
29 Αυγ 2021 · Use the metre ruler to measure out intervals on the bench, e.g. every 0.2 m for a total distance of 1 m. Draw straight lines with pencil or chalk across the table at these intervals; Attach the bench pulley to the end of the bench; Tie some string to the toy car or trolley.
Investigate the effect of varying the mass of an object on the acceleration produced by a constant force. Draw a series of straight lines, each 20 cm apart, perpendicular to the edge of the bench. Attach the car to the string at one end, with the other end running across the bench pulley.
