23. Design a helical compression spring using round steel wire, ASTM A227. The spring will actuate a clutch and must with- stand several million cycles of operation. When the clutch discs are in contact, the spring will have a length of 60 mm and must exert a force of 90 N. When the clutch is disengaged, the spring will be 50 mm long and must exert a force of 155 N. The spring will be installed around a round shaft having a diameter of 38 mm. helical compression spring 23. Design a helical compression spring using round steel wire, ASTM A227.
