A spiral spring is compressed by 0.3m.calculate the stored energy in the spring if force constant is 300Nm-1

Answer 1

The formula to calculate the stored energy in a spring is given by:

U = (1/2)kx^2

Where U is the stored energy, k is the force constant, and x is the displacement (in this case, the compression) of the spring.

Given:
k = 300 N/m
x = 0.3 m

Substituting the values into the formula:

U = (1/2)(300 N/m)(0.3 m)^2
U = (1/2)(300 N/m)(0.09 m^2)
U = (1/2)(27 N m)
U = 13.5 J

Therefore, the stored energy in the spring is 13.5 Joules.
