Solve the above question if rod has a weight `20 N` uniformly distributed over its length.

A

15 N, 15 N

B

13 N, 17 N

C

18 N, 12 N

D

17 N, 13 N

Text Solution

Verified by Experts

The correct Answer is:
D
(d) `R_1 + R_2 = 10 + 20 = 30 N`
`Sigma tau_A = 0 rArr R_2 xx 1 - 10 xx 0.3 - 20 xx 0.5 = 0`
`rArr R_2 = 13 N, R_1 = 30 - R_2 = 30 - 13 = 17 N`.
