A flat spiral spring has a retangular cross-section 10 mm x 0-5 mm and a length of 400 cm. The maximum bending stress induced in the spring wire is 620 MPa. Calculate (a) the couple exerted on its central spindle, (b) number of turns the spindle can make before the spring is run down and (c) the amount of energy stored in the spring. Take E = 200 GPa. %3D
