If the work done in stretching
WebThe work done in stretching or compressing a spring is proportional to the square of the displacement. If we double the displacement, we do 4 times as much work. It takes 16 J to stretch the spring 20 cm from its unstretched length, so it takes 12 J to stretch it from 10 cm to 20 cm. Or, formally: W = ½kx 2 . Web27 mrt. 2024 · Studies show that there are many benefits of stretching, including reducing neck and shoulder pain. Plus, regular breaks to stand and stretch increase productivity. 2 Flexibility breaks allow your eyes to …

Web1. Strain energy and work done in the tensile test As a tensile specimen extends under load, the forces applied to the ends of the test specimen move through small distances. … WebAnswer (1 of 2): The work done will be F\times l. See the figure below, it shows the graph of force vs deformation. The rectangular area \ F\times l represents the work done when a constant force of magnitude \ F is suddenly applied. (The process is no more quasi-static.) The wire will store, d...

So where does the other half go? • ( 18 votes) define kinesthesiaWeb16 nov. 2024 · In a first course in Physics you typically look at the work that a constant force, F F, does when moving an object over a distance of d d. In these cases the work is, W =F d W = F d. However, most forces are not constant and will depend upon where exactly the force is acting. So, let’s suppose that the force at any x x is given by F (x) F ( x). feeling weak after eating healthy
