1- The steel compression strut BC of the frame ABC in the figure below is of tubular cross section with an outer diameter of 40 mm and a wall thickness of 4 mm. a) Determine the factor of safety against elastic buckling of BC if the 30,000 N load shown below is applied at the mid point between A and B. Let E = 205 GPa and yielding = 380 MPa. b) What is the wall thickness that BC can have if the buckling safety factor was 3? 30,000 N 1.0 m 2.0 m
