Web20 mrt. 2024 · In this analogy, stress equation derived for the bar to be taken equivalent to the actual helical spring. DIMENSIONS OF EQUIVALENT BAR: 1. The diameter of the bar always taken equal to the Wire diameter of the spring (d). 2. We know; length of one coil in the spring= π D. And ,we have N active coils. Therefore, length of equivalent bar = πDN WebANS: n = 14 turns STRENGTH OF MATERIALS VI. HELICAL SPRINGS 4) Compute the maximum shearing stress developed in a phosphor bronze spring having mean diameter of 200 mm and consisting of 24 turns of 200 mm diameter wire when the spring is stretched 100 mm.
