A flat spiral steel spring is to give a maximum torque of 1500 N-mm for a maximum stress • Find the thickness and length of the spring to give three complete turns of motion, when the stress . decreases from 1000 to zero. The width of the spring strip is 12 mm. The Young's modulus for the material of the strip is 200 kN/mm2.
