A machinery uses a helical tension spring with wire diameter of 3 mm and coil outside diameter of 35 mm. The spring has 9 total coils. The design shear stress is 500 MPa and the modulus of rigidity is 82 GPa. Determine the force that causes the body of the spring to its shear stress in N. Consider ground ends. Type of ends Ground Plain Squared & Ground Squared Active coils na = NT na =nT na =nT 2 na = NT-2 -
