Question

Hooke's Law

Objective: To verify Hooke’s law that the extension of a spring is proportional to the stretching force applied once the elastic limit is not exceeded.

1. a) Mention at least three important precautions that you take while performing the experiment? b)Give one example where Hooke’s law can be applied. c) Draw the forces experienced by the mass spring system. d) Name the forces and state the law applicable here. e)  If a mass of 250 grams is suspended, then find the values of these forces that you have mentioned. (Clear and Legible writing please and thank you)

Answer 1

The experiment for hooks law :- evaluation of spring constant and extension of the spring with different masses!!.. all of ur answers are given below.

a) precautions-

1)Be sure to keep your feet out of the area in which the masses will fall if the spring or rubber band breaks!

2 )Besure to clamp the ring stand to the lab table, or weight it with several books so that the mass does not pull it off the table.

3)You need to hang enough mass to the end of the spring to get a measurable stretch, but too much force will permanently damage the spring. (An engineer would say that it has exceeded its "elastic limit"). "You break it, you bought it."

b) a weight hanging from a spring !!! By evaluation of spring constant and the extention of the spring per weight .. we can show the hooks law .
