For finding the maximum height of a mountain on the earth, we have to consider

A

Tensile stress and Poisson's ratio

B

Bulk stress and Poisson's ratio

C

Bulk stress and Shearing stress

D

Shearing stress and Tensile stress

Text Solution

Verified by Experts

The correct Answer is:
B
The material at the bottom of the mountain experiences the bulk stress i.e.,
`("Weight of the mountain")/("Area of cross-section") = (A h rho g)/(A) = h rho g` ltbgt in the vertical direction (similar to hydrostatic pressure).
But the sides of the mountain are not confined as in the case of a liquid. As they are open, we have also to consider the shear stress, in addition to bulk stress.

The maximum height of a mountain on earth is limited by the rock flowing under the enormous weight above it. Studies show that maximum height depends on young’s modulus (Y) of the rod, acceleration due to gravity (g) and the density of the rock (d). (a) Write an equation showing the dependence of maximum height (h) of mountain on Y, g and d. It is given that unit of Y is Nm^(-2) . (b) Take d = 3 xx 10^(3) kg m^(-3), Y = 1 xx 10^(10) Nm^(-2) and g = 10 ms^(-2) and assume that maximum height of a mountain on the surface of earth is limited to 10 km [height of mount Everest is nearly 8 km]. Write the formula for h.

If a pendulum swings with the same period at the top of the mountain and at the bottom of the mine then the ratio between height H of a mountain and the depth h of a mine is :
