Principle

Make und calibrate a spring dynamometer unsing a helical spring. Subsequently, determine the weight in N of a test piece with the model.

Benefits

Optimised for demonstration experiments: Transformation from horizontal into vertical direction
Very good visibility: Big devices on uniform background
Strong Magnets (at least 10 N) allow a safe mounting and therefore a very easy handling
Demonstrative measurement of forces with large circular dynamometers with a fixing magnet and ball-bearing pulley with two cord grooves for two measuring ranges
Colored arrows enhancing observations and explanations
