Solved: For the wire form shown, the wire diameter is d,
Chapter 10, Problem 10-42(choose chapter or problem)
For the wire form shown, the wire diameter is d, the length of the straight section is l, and Young’s modulus is E. Consider the effects of bending only, with \(d \ll R\).
(a) Use Castigliano’s method to determine the spring rate k.
(b) Determine the spring rate if the form is made from 0.063-in diameter A313 stainless wire with \(R = \frac{5}{8}\) in and \(l = \frac{1}{2}\) in.
(c) For part (b), estimate the value of the load F, which will cause the wire to yield.
