Force on a pulley mounting

Principle

The students should

1. With the aid of a pulley deflect a weight (force) and measure the resultant force F_r acting on the mounting of the pulley.
2. Change the angle α between the weight (force) F_g and the deflected force F₁ and once again determine the resultant force.

In a supplementary problem the students who are familiar with the trigonometric functions should calculate the resultant force F_r using F₁, F_g and the angle α.

The protractor sheet (circle with angular divisions) which is required for the evaluation is provided as a master which can be copied. The xerox copies should be given to the students before they begin the experiment.

Benefits

• Real stand material for an esecially stable and safe setup
