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

To calculate the stored energy in the spring, we can use the formula:

E = (1/2) * k * x^2

where E is the stored energy in joules, k is the force constant in N/m, and x is the compression or extension of the spring in meters.

Given:
Compression of the spring, x = 0.3 m
Force constant, k = 300 N/m

Let's substitute these values into the formula:

E = (1/2) * 300 N/m * (0.3 m)^2

E = (1/2) * 300 N/m * 0.09 m^2

E = 13.5 J

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