Determine the permissible shear stress, Mechanical Engineering

Assignment Help:

A helical compression spring is used to take the shock. The initial compression of the spring is 30 mm and it is further compressed by 50 mm while absorbing the shock. The spring is to absorb 250 J of energy during the procedure. The spring index will be taken as 6. The spring is made of patend and cold drawn steel wire with ultimate tensile strength of 1500 N/mm2 and modulus of rigidity of 81370 N/mm2 . The permissible shear stress for the spring wire could be taken as 30 % of the ultimate tensile strength. Design the spring.
