1. Design and check for stability for a square and ground endhelical spring subjected to a maximum force of 1300 N supportedbetween flat surfaces. The deflection of the spring correspondingto the maximum force should be approximately 25mm. The materialused for the spring is cold drawn steel wire with ultimate tensilestrength, modulus of elasticity and rigidity of 1090, 207000 and81730 MPa, respectively. Assume and state relevant parameters.
