Продукт No: P0999269

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.

Benefits

  • Student-suitable experiment ...

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 force with the given weight (force) ...

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  F2. Without knowledge of the trigonometric functions, the evaluation ...

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 α between the weight (force) Fg and the deflected force F1 and once again determine the ...

Finding the center 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 different suspension points.
  • In each case ...

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 ... ...

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The beam supports have been replaced by suspending treads so that the forces can be better measured with spring ...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

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 influence of a load on one end of ...

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 and F / Fg and compare them with each other. From the ...

Friction

Principle

With the aid of the friction block the students should observe that different surfaces result in different frictional forces. The sliding properties of the interacting surfaces should be especially stressed.

Further, the difference between static friction and ...

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 each case. A graph of these results ...

Double-sided lever

Principle

On a double-sided lever the students should verify the law "force × force arm = load × load arm" and be able to present it as a formula.

In a supplementary problem the term moment of rotation can be treated and the law of the ...

One-sided lever

Principle

In Experiment ME 3.2 (Double-sided lever) the students became familiar with the law of the lever and its representation in the form "Sum of all moments of rotation equals zero". In this experiment they should investigate the one-sided lever in the same way and establish its ...

Force and displacement on a fixed pulley

Principle

The students should deflect a force with a fixed pulley and determine whether the forces and distances are changed by doing this.

Further, through experiment and calculation they should determine whether the products of load × load distance and force × ...
