L = 5
d = 2*10^-3
r = 10^-3
A = pi r^2 = pi (10^-6)
stress = 50 N / 3.14*10^-6 = 15.9 * 10^6 Newtons/ m^2
strain = delta L/L = .25*10^-3 / 5 = .05 *10^-3 = 50 * 10^-6 m
E = stress / strain
A wire of 5.0m and diameter 2.0mm,extends by 0.25mm when a force of 50N was stretch it from it's end calculate
a.the stress on the wire. b.the strain in the wire. c.the young's modulus of elasticity of the wire
