//Given
//Variable declaration
A=700 //Area in sq.mm
L=1.5*10**3 //Length of a metal bar in mm
sigma=160 //Stress at elastic limit in N/sq.mm
E=2e5 //Youngs Modulus in N/sq.mm
//Calculation
V=A*L //Volume of bar in sq.mm
Pr=(sigma**2/(2*E)*V)*1e-3 //Proof resilience in N-m
P=int(sigma*A/2*1e-3) //Suddenly applied load in kN
