Uses of the ball bearing pulley on a boss
The pulley is clamped to a stand rod wherever a low-friction change of direction is needed for a string, such as leading a hanging mass over the edge of a set-up, and the three mounting planes let it be arranged for horizontal, vertical or sideways pulls.
- Guiding a string and hanging mass in force and acceleration experiments
- Building pulley arrangements on stands for mechanics practicals
- Force table and equilibrium set-ups that need an extra pulley
- Low-friction pulley for demonstrations with trolleys and tracks
