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 50 kg girl whose leg bones are 5m^2 in area and 50 cm long falls from a height of 2 m without breaking her leg bones.If the bones can stand a stress of 10^8 Nm^(-2) ,calculate the Young's modulus for the material of bones.

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?

Find the maximum energy per unit volume that can be stored in a metal wire when stretched, if its breaking stress is 1.3 xx 10^(8) Nm^(-2) and Young's modulus of the material is 2.2 xx 10^(11) Nm^(-2) .

A uniform wire 6 m long weighing 40 g elongates by 0.8 mm when stretched by a load of 1 kg. If its density is 8.9 g cm^(-3) , Find young's modulus of the material.

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

If a compressive force of 3.0xx10^(4)N is exerted on the end of a 20 cm long bone of cross-sectional area 3.6cm^(2) (i) will the bone break and (ii) if not by how much length does it shorten? Given compresive strength of bone =7.7xx10^(8)N//m^(2) and young's modulus of bone =1.5xx10^(10)N//m^(2)
