A helical spring used in an automobile suspension is having a wire diameter of 7mm and an outside diameter of 72mm. The spring has 16 active coils. If the permissible shear stress of the spring material is 345 N/mm2 and the Modulus of rigidity is 83 kN/mm2.   a) Calculate the axial load in N and the deflection of the spring in mm, considering the effect of curvature. b) Calculate the value of axial load in N neglecting the effect of curvature.

Problem 2 You will be determining the value for the external load P that will cause the diameter of BC to change to 5.8 mm. The original diameter of BC is 6 mm. Use the values given below unless otherwise stated by the questions. E = 200 GPa V = 0.38 300 mm 400 mm B 1 -200 mm-
