A beam of weight `W` supports a block of weight `W`. The length of the beam is `I`. and weight is at a distance `L/4` from the left end of the beam. The beam rests on two rigid supports at its ends. Find the reactions of the supports.

Text Solution

Verified by Experts

`R_(1)+R_(2)=2W`

Balancing torque about `A`
`R_(2)L=WL/4+WL/2`
`R_(2)=(3W)/4` and `R_(1)=(5W)/4`
