Assuming that shear stress of base of a mountain is equal to force per unit area to its weight, calculate the maximum possible height of a mountain on the earth if breaking stress of a typical rock is 30×107Nm−2 and specific gravity is 3×103kg/m3.
(a) p=WA=hpg≤Breakingstress
or h≤Breakingstresspg=3×1083×103×10
h≤10km
