FORCES

In any elastic body, extension and tension are proportional to one another. This relationship was discovered by Robert Hooke and is frequently demonstrated using a coil spring with weights suspended from it. The change in the length ... more

Objective: Confirm Hooke’s law for coil springs under tension In any elastic body, extension and tension are proportional to one another. This relationship was discovered by Robert Hooke and is frequently demonstrated using a coil spring ... more

Objective: Verification of the law of the lever The law of the lever follows from the equilibrium of moments, which works for all three classes of lever. It represents the physical basis for all kinds of mechanical transmission of force. more

Objective: Experimental investigation of the vector addition of forces The vector addition of forces can be demonstrated in a clear and simple manner on the force table. The point of action of three individual forces in equilibrium is exactly ... more

Objective: Determine the forces acting on an inclined plane If a body needs to be propelled up an inclined plane, it is not the body’s full weight G which needs to be overcome, but only the component which acts parallel to the plane F1. ... more

Objective: Measurement of friction forces In order to measure dynamic friction, a friction measuring apparatus is used. It is composed of movable friction strips, which are pulled from under a stationary rough body connected to a dynamometer ... more
