Calculate the Young’s modulus in the cantilever depression method. The length is 1m which is suspended with a load of 150gm. The depression is found to be 4cm. The thickness of the beam is 5mm and breadth is 3cm.
(a) 3.92 × 10^10 N/m^2
(b) 9000 × 10^10 N/m^2
(c) 4000 × 10^10 N/m^2
(d) 1.245 ×10^10 N/m^2
The question was asked by my college professor while I was bunking the class.
The origin of the question is Elasticity in chapter Thermal Properties of Matter of Engineering Physics I
