1.	A metallic rod breaks when strain produced is 0.2%. The Young's Modulus of the materials of the rod is .What should be its area of cross-section to support a load of 104N
Answer» From Young’s Modulus FORMULAE: Y = Fl’/Al where L’ = 2l/1000 putting all the values we get, 7 x 10^9 = 10^4 * 2l/1000Al solving we get, A = 1/1400 m^2.
