Principle
The students should
- With the aid of a pulley deflect a weight (force) and measure the resultant force Fr acting on the mounting of the pulley.
- Change the angle α between the weight (force) Fg 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 Fr using F1, Fg 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
- Student-suitable experiment descriptions with reports available
