Bending of a leaf spring

Principle

1. The students should investigate the behaviour of a leaf spring under load, make a graph of the measuring results and - most importantly - determine the spring constant D (see also Experiment ME 2.4).
2. In the course of the same experiment, the (tractive) force should be determined at different angles for the same deflection and an explanation of the results should be attempted.

Task

How does a leaf spring behave under load?

You will investigate the behaviour of a leaf spring under load, make a graph of the measuring results and determine the spring constant D.

In the course of the same experiment you will determine the force at different angles for the same deflection.
