Force versus displacemetn curve is shown...

Force versus displacemetn curve is shown in the diagram. Find the wor done by the forfe at the end of the displacements
(i) 10m (ii) 20 m (iii) 30m

Text Solution

Verified by Experts

As we know that work done is area under F-s curve.

(i) Work wond at the end of 10m `W=A_(1)` (Area from 0 to 10) `=1/210 10J =50J`
(ii)Work done at the end of 20 m `W=A_(1)+A_(2)` (Area from 0 to 20 m) `=50+50=100J`
(iii) Work done at the end of 30 m `W=A_(1)+A_(2)+A_(3)` (Area from 0 to 30m)
`=50+50-(A_(3)=-50)=50J`
