Force and displacement on a free pulley

Principle

  1. The students should determine the forces which occur on both supporting lines of a movable pulley when it is loaded with various masses.
  2. Further, they should change the point of impact of the force (the force distance) and examine the effect on the load (load distance). ...

Block and tackle formed from a free and a fixed pulley

Principle

The students should recognize on a simple block and tackle that the force required to lift a specific load can be reduced by half compared with the weight (force) by using an arrangement of 2 pulleys. However, a longer distance must be covered. By comparing the products ...

Block and tackle with four pulleys

Principle

Using a block and tackle as an example, the students should observe that the force, which is necessary to lift a given load, decreases in direct correlation with the number of pulleys.

  1. They should determine how much larger the weight force of the load is compared ...

Force and displacement on a step wheel

Principle

  1. The students should measure the forces which maintain equilibrium with different load masses on a step wheel.
  2. They should measure the force and the length of the load arms of a step wheel, and calculate the products load × load arm ...

Gear mechanisms and belt drives

Principle

On both a single-stage gear and belt drive, the students should determine the sense of rotation of the driven and the driving wheel as well as the drive ratios. The students should compare the ratios obtained experimentally with the ratios of the number of teeth of the gears and ...

Hydrostatic pressure

Principle

The students should determine the directional independence of hydrostatic pressure (termed as top, lateral and bottom pressure) with the aid of 3 hydrostatic pressure probes.

Additionally, they should measure the hydrostatic pressure as a function of immersion depth ...

Buoyancy and floating

Principle

The students should determine whether or not various objects float in water. They should then investigate whether the volume of an object or its shape affect its buoyancy.

Archimedes' principle

Principle

The students should determine the weight (force) of an object in air and then in water. From the difference they should calculate the buoyancy Fb

In a second experiment, the students should determine the mass of the water displaced by the immersed object; from this ...

Finding the density of solid bodies by measuring the buoyan-

Principle

In this experiment the students should recognize that the density of solid objects can be determined by measuring only the buoyancy. The required computations can be given or worked out by the students on their own, in part as an additional Task.

Benefits
