A coiled spring with 5 cm of outside diameter is required to work under the load of 190 N. The wire diameter is 5 mm, the spring is to have 6 active coils and the ends are to be closed and ground. Determine the total number of coils. The modulus of rigidity is 809 GPa and the mean radius is to be 23 mm, with 7 mm pitch of the spring
