W=1000 kg convert this load into UDL of half span of the arch then UDL load,w=200 kg/m
The horizontal thrust formula for half UDL of the arch is =wl/16h.
So, H=wl/16h=200*10/16*1=1250 kg.
The horizontal thrust formula for half UDL of the arch is =wl/16h.
So, H=wl/16h=200*10/16*1=1250 kg.

W = 1000 kg convert this load into UDL of half span of the arch then UDL load,
w = 200 kg/m.
The horizontal thrust formula for half UDL of the arch is = wl * l/16h.
So, H = w(l*l)/16h
= 200 * 10/16 * 1
= 1250 kg.
w = 200 kg/m.
The horizontal thrust formula for half UDL of the arch is = wl * l/16h.
So, H = w(l*l)/16h
= 200 * 10/16 * 1
= 1250 kg.

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.

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.

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.
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?

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

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