Work Done By A Variable Force (Tangential Effort)- Engineering Lab Training Systems.
Features
Low cost, effective teaching
Self-contained
Bench mounted
Reinforces concepts of work and energy
Direct reading of tangential effort
Three year warranty
Range of Experiments
To
obtain the experimental relationship between effort and distance moved
by effort, and to compare with a theoretical prediction
To show that the work done is the area under a graph of load against distance moved
Description
This
experiment is designed to reinforce the general principle that the work
done, particularly by a variable force, can be determined simply by
measuring the area under the graph of force and distance moved. The
equipment is deliberately simple so that concepts are readily grasped.
It is a companion experiment to HFC6, which is concerned with the work
done by available vertical force.
A pivoted arm carrying a weight
at its end is restrained by a spring balance at right angles to the
arm. The angular position of the arm is indicated by a protractor scale.
The
effort is the force needed to hold the weighted arm at a particular
angle. This can be repeated for several different weights.
This
equipment is part of a range designed to both demonstrate and
experimentally confirm basic engineering principles. Great care has been
given to each item so as to provide wide experimental scope without
unduly complicating or compromising the design. Each piece of apparatus
is self-contained and compact. Setting up time is minimal, and all
measurements are made with the simplest possible instrumentation, so
that the student involvement is purely with the engineering principles
being taught. A complete instruction manual is provided describing the
apparatus, its application, experimental procedure and typical test
results.
