A particular machine requires a helical compression spring, having ends squared and ground, to support an essentially static load of 500 lb. The spring constant is to be 200 lb/in., and the stress at the design load is to be 80 ksi. The clash allowance is to be 0.10 in. The dimensions of related parts establishes that D should be 3 in. Determine N, d, and Lf .
