Formula is wl/8. So answer 1000 * 10/8 = 1250 kg.

Formula is WL/8H. So answer is 1250.

Va = 750kg & Vb = 250kg.
Moment at crown due to external loading.
= Vb *l/2.
= 250 * 5.
= 1250kg m.
Horizontal thrust = 250/1=1250 kg.

What is the formula for concentrated load?

Achut Paudel said:   10 years ago
@Tej Deuba,

This formula is for UDL. For a concentrated load, formula should be different.

H = wl2/8h this formula is not apply when apply H = 781kg why answer is 1250kg.
