If a spring extends by x on loading, then what is the energy stored by the spring. ( If T is tension in the spring and K is spring constant

Why steel in used to make springs ?

A long spring stretched by 2 cm and it's potential energy is U. If the spring is stretched by 10cm, the potential energy stored in it will be

state true false. The stretching of a coil spring is determined by its shear modulus.

A spring weighing machine inside a stationary lift reads 50kg when a man stands on it. What would happen to the scale reading if the lift is moving upward with constant acceleration?

A spring weighing machine inside a stationary lift reads 50kg when a man stands on it. What would happen to the scale reading if the lift is moving upward with constant velocity

A soap bubble of radius 'a' is blown so that it's diameter is doubled. If T is surface tension of water, the energy required to do this at constant temperature, calculate?

A spring is kept compressed by trying its ends together tightly. It is then placed in acid and dissolved. What happened to it's stored potential energy ?

A body of mass 100 gram is suspended from a light spring which stretches it by 10 cm. Find the force constant of the spring.
