What is the work done by spring?
What is the work done by spring?
Also, we can see that in a cyclic process, the work done by the springs force is zero. Hence, we can say that the spring force is a conservative force because it depends on the initial and final positions only. Therefore, this work done is in the form of the Spring potential energy.
Can work done by spring force be positive?
Total work done by spring force may be positive, negative or zero. though we know that the spring force is always directed towards mean position and the spring force is always negative.
How much work is done stretching a spring?
The average force you exert as you change the displacement from 0 to x is ½kx. The work you do when stretching or compressing a spring a distance x from its equilibrium position therefore is W = ½kx2.
What is work and work done?
work, in physics, measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement. If the force is being exerted at an angle θ to the displacement, the work done is W = fd cos θ.
How do you calculate the work done by a spring?
When a force is applied on a spring, and the length of the spring changes by a differential amount dx, the work done is Fdx. For linear elastic springs, the displacement x is proportional to the force applied: F=Kx where K is the spring constant.
What is the upper limit of the integral for compressing the spring?
We start compressing the spring at its natural length ( 0 m) and finish at 0.25 m from the natural length, so the lower limit of the integral is 0 and the upper limit is 0.25. So: (b) What is the work done in compressing the spring a further 30 cm?
What is an example of work as an integral?
Integrals: Work as an Integral. The work, W, performed moving an object from x=a to x=b by a force F(x) may be attained by the following: Example: A spring exerts a restoring force of 0.2 newtons when it is compressed 0.4 meters.
How do I extend or compress a spring?
Extend or compress the spring by dragging the mass. See the force required to do this. (You can drag the mass when it goes green.) When you let go, you will see the work done in compressing or extending the spring. Change the value of k using the slider and see how much this changes the force required and the work done.
