The cross section of one type of weight-bearing rod (the surface you would get if you sliced the rod perpendicular to its axis) used in the Olympics is a circle, as shown in the figure. The rod can handle a stress of 10,000 pounds per square inch (psi). The relationship between the stress S the rod can handle, the load F the rod can carry, and the diameter d of the cross section is given by the equation Sπ (d/2)2 = F. Assuming that d = 1.5 inches, find the load the rod can support. Use t ≈ 3.14 in your calculation.
