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.Continue Reading
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
To calculate the normal force on an object, draw a free body diagram, determine the surface's angle, factor in the other present forces, and solve for the normal force. Note that the normal force is perpendicular to the surface the object sits on.Full Answer >
Angular magnification is the magnification done by optical instruments with an eyepiece, where the ratio of an angle is delimited at the eye when using the instrument divided by the angular size without the instrument. A simple magnifier achieves angular magnification by permitting the placement of an object closer the eye than the eye's ability to focus in normal circumstances. The normal close focus distance in angular magnification is 25cm.Full Answer >
A thedolite is an instrument used to measure horizontal and vertical distances using lenses and lines. They include several components, such as a telescope, a leveling mechanism, a tripod and a compass. Theodolites are used for surveying and construction to obtain precise readings of landforms so construction projects remain level and plumb with the ground.Full Answer >
Things work because their fundamental forces allow them to. To better understand how something works, that thing may be made into the subject of a physical experiment. Discovering how a thing works is done through scientific experimentation or through observing it and making an informed assumption of the thing's properties and functions. Sometimes, a thing seems to function one way but may work differently than first expected or have workings that are not easily spotted on the surface.Full Answer >
