Two steel springs arranged in series supports a load of 3849.35 N. The upper spring has 12 turns of 25-mm diameter wire on a mean diameter of 200 mm. The lower spring consists of 10 active coils of 20-mm diameter wire with a mean diameter of 150 mm. If the maximum shearing stress in either spring must not exceed 220 MPa, determine the total deflection of the assembly. a. 170 mm b. 180 mm c. 160 mm d. 150 mm
