Ashear force of 400 n is applied to one face of an aluminum cube with sides of 30 cm. what is the resulting relative displacement? (the shear modulus for aluminum is 2.5 x 1010n/m2).

a) 4.4 x 10-8 m
b) 8.2 x 10-8 m
c) 1.9 x 10-8 m
d) 5.3 x 10-8 m

So option (d) will be correct option

Explanation:

We have given shear force F = 400 N

Size of the cube

Shear modulus of aluminium

We have to find the resulting relative displacement

Area of the cube

We know that shear force is given by

So

So option (d) will be correct option
