Extracted text: Problem I. The loaded steel framing shown consists of bars 1, 2, and 3 with their corresponding flexural rigidity, EI. The leftmost side is clamped (fixed support), the opposite side hinged, and a roller support at the middle. If each bar may be subjected to Euler buckling and a = 3 m, Note: Joints where members meet can be treated as pin. Refer to the given table for values of P and I1. 211 = I2 GIVEN P (kN) 1 (x10° mm*) P 176.0 4.137 EI2 a EI (1) 3 2a a →- a →| а. Determine the critical load for each member. b. Calculate the factor of safety (F.S.) of the whole frame against buckling. с. At what value of P will the frame start to have a buckled member?
