What is the mechanical work done by the initial load placed on a fiber if the fiber is linearly deformed by 3 nm?

Explanation:

The mechanical work done by the load placed on a fiber if the fiber deforms by 3 nano-meter can be given in relation to the energy stored in a stretched fiber.

The energy stored in a stretched fiber is equal to the work done:

where:

k = stiffness constant

deformation in the fiber =
