Pa = 1/2*ka*r*H^2.
Ka = 1-sin30/1+sin30.
So, ka = 0.33.
We take ka=1/3.
Now apply formula,=1/2*1/3*2*9*9.
= 27 tonne.
Ka = 1-sin30/1+sin30.
So, ka = 0.33.
We take ka=1/3.
Now apply formula,=1/2*1/3*2*9*9.
= 27 tonne.

Pa=Ka.6v= 0.33(2*Z)=0.66Z --------t/m2.
at Z =0, Pa= 0.
atZ =9, Pa= 5.94.
F = 0.5 * 5.94 * 9 = 26.73 t/m.
at Z =0, Pa= 0.
atZ =9, Pa= 5.94.
F = 0.5 * 5.94 * 9 = 26.73 t/m.
