A prismatic bar of length L is fixed between two rigid supports A and B at its ends. If an axial load P is applied at a distance of L/3 from support A, what will be the support reactions RA and RB?
- 1RA = P2, RB = P2
- 2RA = P, RB = P
- 3RA = 2P3, RB = P3✓
- 4RA = P3, RB = 2P3
Correct answer
RA = 2P3, RB = P3
