The instrument used to measure force is called a dynamometer. A dynamometer is capable of measuring different kinds of force such as mechanical force and muscular force.Know More
These instruments are used for a wide range of tasks including measuring the power of an engine, measuring the grip strength of a person and studying combustion. Physical therapists and engineers are among the professionals that utilize dynomometers in their work.
There are several kinds of dynomometers such as dry friction dynomometers, Eddy current dynomometers and hydraulic dynomometers. The word dynamometer comes from the French word 'dynamis' meaning power and 'metre' meaning meter. A similar instrument is the anemometer.Learn more about Physics
Contact forces are those forces that cause a change in another object because the objects are physically touching one another, according to Reference.com. Examples of contact forces include applied force, tension force, air resistance force and normal force.Full Answer >
The forces associated with a press, or interference, fit are determined using equations and pre-established values. These equations assume that the shaft is treated as a cylinder with a uniform external pressure, and the hub is treated as a hollow cylinder with uniform internal pressure.Full Answer >
Non-contact forces arise from long-range interactions, such as gravity and electromagnetism. Weight is an example of non-contact force, as objects are attracted to massive bodies without touching them.Full Answer >
Electricity, gravity and magnetism are all examples of non contact forces. A force is anything that can cause a physical change in an object.Full Answer >
