The force-extension graph of an elastic ...

The force-extension graph of an elastic wire subjected to a certain force is as shown in Figure. From the graph calculate the work done in stretching the wire.

Text Solution

Verified by Experts

Work done in streteching the wire
` = ( 1)/( 2) Fl`
= Area of the triangle OAB
`= ( 1)/( 2) xx 300 xx3 xx 10^(-3)`
`= 0.45J`
