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 sa ...

Bending of a leaf spring

Principle

Leaf springs are thin metal plates that are elastically deformed under load: When a force is applied to a
leaf spring, then it is subject to deformation. A characteristic of such an elastic deformation is that the
original shape is re-for ...

Calibration of a dynamometer

Principle

The students should add a scale to an uncalibrated spring balance by loading it with mass pieces.

In doing so they should know that a mass of 100 g represents a weight (force) of 1 N in the gravitation field of the earth.

Product-No: P0999300

Force aligned in the same and opposite direction

Principle

On the one hand, the students should investigate the effect of two forces acting in the same direction on a mass piece; on the other hand, the effect of two forces acting in opposite directions on it.

From the comparison of the two measured ...

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 which replaces the two different forces  F1  and

Product-No: P0999500

Resolution of forces on an inclined plane

Principle

The students should - experimentally - gain knowledge of the resolution of the weight (force) Fg of a car on an inclined plane into a normal force Fn ,acting perpendicular to the track, and a downhill force

Product-No: P0999600

Force on a pulley mounting

Principle

The students should

  1. With the aid of a pulley deflect a weight (force) and measure the resultant force Fr acting on the mounting of the pulley.
  2. Change the angle ? between the weight (force) F

Finding the centre of gravity

Principle

  • The students should determine the center of gravity of regulary-shaped objects by balancing them on the point of a pencil.
  • They should determine the center of gravity of an irregulary-shaped object with at least two plumbs from diff ...

Product-No: P0999800

Stability

Principle

By pulling a block at a point above its centre of gravity against an obstacle at its base, the students should observe that an object always tips over when the trace of a plumb through its centre of gravity lies outside its supporting base.

Reaction forces for an unloaded beam

Principle

The students should determine the load pressures on an unloaded beam with (1) symmetrical and (2) unsymmetrical beam suspension.

The beam supports have been replaced by suspending treads so that the forces can be better measured with spring ...

Product-No: P1000000

Reaction forces for a loaded beam

Principle

Having completed their measurements on an unloaded beam (see ME 2.13), the students should now determine the effect of a load on the loading pressure in dependence on the point of application of the load to the beam.

In the evaluation the in ...

Product-No: P1000100

Restoring force on a displaced pendulum

Principle

The students should measure the restoring force F of a deflected pendulum as a function of the deflection x for two different pendulum lengths.

Additionally, they should calculate the ratios x / l

Product-No: P1000200

Friction

Prinzip

Die Schüler sollen mit Hilfe eines Reibungsklotzes herausfinden, dass unterschiedliche Oberflächen unterschiedliche Reibungskräfte hervorrufen. Besonderer Wert ist auf die Gleiteigenschaften der aufeinander wirkenden Oberflächen zu legen.

Weit ...

Product-No: P1000300

Coefficient of friction

Principle

Using a friction block, the students should establish that the frictional force is independent of the surface area.
For a constant surface area the students should vary the mass of the friction block and measure the frictional force Fr in e ...

Product-No: P1000400

Beam balance

Principle

In Experiment ME 2.3 [Weight (force)] the students determine the mass of different objects with a spring balance (dynamometer). They measured the force with a mass experiences under the influence of the earth's gravity. In contrast to this, measuremen ...
