Combination of forces; parallelogram of forces

Principle

Based on their knowledge of Experiment ME 2.7, the students should determine the direction and magnitude of the resultant force  F_r  which replaces the two different forces  F₁  and  F₂. Without knowledge of the trigonometric functions, the evaluation can be performed graphically with the aid of a force parallelogram or it can be calculated as a supplementary problem, if the students are familiar with the trigonometric functions.

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
