A helical coil spring is made from a steel (G = 80x10^9 N/m^2) rod of length 1.44 m and diameter 6 mm. The rod is formed into a helix of coil radius 2.4 cm. The entire rod is used in the helix. (a) What is the stiffness of the spring? (b) What is the maximum force that can be applied to the spring so that the shear stress does not exceed 200 MPa. (c) What is the static deflection of the spring when a 60 gram particle is hung from the spring? (d) Derive the governing differential equation for the displacement of the 60 gram particle mass hanging from the spring measured form the equilibrium position of the system when the particle is subjected to a force of F(t)=0.1sin100t N
