Member AB (helical spring) and Member AC (axial rod) are carrying a weight at point A. Member AB has the following properties: R = 90 mm, n =4 turns, G = 70 GPa, d = 30 mm, and Tallow = 105 MPa while Member AC has the following properties: L= 2, A= 500 mm2, E 200 GPa, and oallow = 30 MPa. Determine the maximum safe value of W (in N). Use simplified formula for the helical spring.
