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

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

What is the formula for concentrated load?

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

= Vb *l/2.
= 250 * 5.
= 1250kg m.
Horizontal thrust = 250/1=1250 kg.

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

Wl/2 = 1000*2.5/2 = 1250kg.

It's WL/4H.
W=1000KG.
L= CENTER TO CENTER=5.
H= RISE =1.
SOLVE IT =1250KG.
W=1000KG.
L= CENTER TO CENTER=5.
H= RISE =1.
SOLVE IT =1250KG.

The formula is H= W*X / 2h, Where X= L / sq.rt3, but X value is directly given in question, X=2.5m.
h=1m and Span is 10m.
H = (1000 kgx 2.5m)/ (2 x 1m) = 1250 kg.
h=1m and Span is 10m.
H = (1000 kgx 2.5m)/ (2 x 1m) = 1250 kg.
