The coiled spring has n coils and is made from a material
Chapter 14, Problem 14-38(choose chapter or problem)
The coiled spring has n coils and is made from a material having a shear modulus G . Determine the stretch of the spring when it is subjected to the load P . Assume that the coils are close to each other so that \(\theta \approx 0^{\circ}\) and the deflection is caused entirely by the torsional stress in the coil.
