Question

A beam AB of length 5 m supported at A and B carries two point loads W1 and W2 of 3 kN and 5 kN which are 1 m apart. If the reaction at B is 2 kN more than that at A, find the distance between the support A and the load 3 kN.

Answer 1

the ratio of  and  is

Explanation:

Let the reaction at B = R

Then Reaction at A = 2R

In vertical direction, the forces will be equal

Thus

 ..............(1)

Again Moment with respect to any point will be zero

Taking moment w.r.t. A
