A horizontal beam AD, 10 m long carries a UDL of 160 N/m together with a concentrated load of 400 N at the left and A. The beam is supported at a point B which is 1 m from A and at C which is on the right-hand, half of the beam and x m from the end, D.
If the mid-point is a point of contraflexure which of the following statements are correct.
1
The value of x will be 3.25 m
2
maximum B.M will be 720 N.m
3
The point of contraflexure other than E is at 2.5 m from point A
4
Minimum B.M will be 120 N.m
