A beam is supported at its ends by supports which are `12` metres apart. Since tha load is concentrated at its centre, there is a deflection of `3` cm at the centre and the deflected beam is in the shape of a parabola. How far from the centre is the deflection `1` cm ?

Text Solution

Verified by Experts

The correct Answer is:
`x=sqrt(24)=2sqrt(6)` metres
