5. Determine the allowable axial load PA for a W250 x 67 steel wide-flange column with pinned ends (see figure below) using a Factor of Safety n=1.5 for the following lengths: L-3 m, 5m, 8 m and 10 m. Assume E-200,000 MPa, and G-300 MPa. 7 L A Pl A ISTE Section A-A

A frame ABC consists of a horizontal beam BC which is supported by a round solid rod AB inclined at a 50° angle, as shown below. The ends of the rod AB are flattened to make pin connections at A and B. A vertical load of 5,000 N is acting at the mid-length of the beam. The rod material is a steel with modulus equal to 207 GPa and yield strength of 220 MPa. (a) Using a factor of safety of2.5, determine the diameter of the rod AB. (b) If a clevis joint is used at the pin connection at B, design the pin diameter so that it does not fail in shear. The tensile yield strength of the pin material is 300 MPa. Use a factor of safety between 1.5 and 2.5. 5,000 N В C 5 m 3 m 50° A
