B.M at fixed end = (wl^2)/2,
B.M at distance l/5= wl^2/50 = (BM at fixed end)/25,
Percentage = (M/25M)*100 = 100/25 = 4%.
B.M at distance l/5= wl^2/50 = (BM at fixed end)/25,
Percentage = (M/25M)*100 = 100/25 = 4%.

M = W L^2/2.
Bm @ L/5 = W (L /5)^2/2
= W L^2/50.
(Bm /M) *100 = 4%.
So, I think Option A is Correct.
Bm @ L/5 = W (L /5)^2/2
= W L^2/50.
(Bm /M) *100 = 4%.
So, I think Option A is Correct.

The answer is D.
At L/5 the Bending moment will become M/5. It's 20% of M
At L/5 the Bending moment will become M/5. It's 20% of M

Wl^2 = w/2 * l/5 * l/5.
= wl^2/50.
=wl^2/0÷wl^2/2 *100 = 4.
= wl^2/50.
=wl^2/0÷wl^2/2 *100 = 4.
