A temporary support steel frame (E 200 GPa) is made of 30-mm diameter solid circular steel rods (members AB and CD), and 22-mm diameter solid circular steel rods (members BC and AD), al pin connected at the turnbuckle corners A, B, C, and D (see Figure below). The steel frame is braced by two cables AC and BD. A turnbuckle is fitted to cable AC and tightening it will induce tension 3m in cable AC. Determine the largest allowable tension...
of a brass core (diameter d, -8 mm) surrounded by a steel shell (inner diameter d2 8.75 mm, outer diameter d -10 mm), topped by a rigid cap. A load P compresses the core and shell, which have length L 120 mm.
