Question

1. A steel rod of length 100 cm is fixed at one end and
5 Kg load is applied at the other end. Calculate the
depression in the Young's Modulus is 8 * 10 Pa.
(Diameter = 1cm)
(Ans. 4.16 cm)
2. A load of 2 Kg produces an extension of 1mm in a wire
of 3 m in length and 1mm in diameter. Calculate the
Young's Modulus of the wire.(Ans. 74.84 GPa)
3. Calculate the Poisson's ratio of a material. Given
rigidity modulus n = 3.9 X 10" Nm-* and Bulk
Modulus K = 7.9 X 10 Nm
(Ans. 0.288)
A circular cantilever of radius 1.2 em and length
1.5 m is fixed at one end. In the other end, a load of
2Kg is applied. The young's modulus of the cantilever
is 19.5 x 10 Nm. Find the depression produced
(Ans. 6.9x10 m)​
