A 40 kg boy whose leg are `4cm^2` in area and `50cm` long falls through a height of `2m` without breaking his leg bones. If the bones can stand a stress of `1.0xx10^8(N)/(m^2)`, calculate the Young's modulus for the material of the bone.

A 45 kg boy whose leg bones are 5 cm^(2) in area and 50 cm long falls through a height of 2m with out breaking his leg bones. If the bones can stand a stress of 0.9 xx 10^(8) Nm^(-2) , Calculate the Young's modulus for the material of the bone. Use , g=10 ms^(-2)

A wire increases by 10^(-3) of its length when a stress of 1xx10^(8)Nm^(-2) is applied to it. What is the Young's modulus of the material of the wire?

A metal wire is observed to stretch by one part in a million when subjected to a stress of 8xx10^(4)N//m^(2) . The Young's modulus of the metal is

In order to produce a longitudinal strain of 2xx10^(-4) , a stress of 2.4xx10^(7) Nm^(-2) is produced in a wire. Calculate the Young's modulus of the material of the wire.

A wire 3m long and having cross - sectional area of 0.42m^(2) is found to stretched by 0.2 m under a tension of 1000 N. The value of young's modulus for the material of the wire is

Bulk modulus of a material is 2.5xx10^(11)"dyne"//cm^(2) and Poisson's ratio is 0.4. Then young's modulus for such material ios

(a) A wire 4 m long and 0.3 mm, calculate the potential energy stored in the wire. Young's modulus for the material of wire is 2.0xx10^(11) N//m^(2) .

The length of a wire is 1.0 m and the area of cross-section is 1.0 xx 10^(-2) cm^(2) . If the work done for increase in length by 0.2 cm is 0.4 joule, then Young's modulus of the material of the wire is

On applying a stress of 20 xx 10^(8) N//m^(2) the length of a perfectly elastic wire is doubled. It Young's modulus will be
