A solid steel bar of diameter d1 = 60 mm has a hole of diameter d2 = 32 mm drilled through it (see figure). A steel pin of diameter d2 passes through the hole and is attached to supports.
Determine the maximum permissible tensile load Pallow in the bar if the yield stress for shear in the pin is Ï„Y = 120 MPa, the yield stress for tension in the bar is Ï„Y = 250 MPa and a factor of safety of 2.0 with respect to yielding is required.
