Transcribed Image Text:

= = A steel tube with outer diameter d₁ 80mm and inner diameter d₂ 72mm is designed to withstand tension force P. The steel tube is connected to a rigid bar (diameter d² = 25mm) through the connecting plates (thickness t = 9mm) as figure below to withstand tension force at different angles. In this case, tension force P is vertical downward, and the two ends of the rigid bar is fixed to the wall. The allowable stresses are tension stress in the steel tube, 75MPa; shear stress in the rigid bar, 50MPa; and bearing stress between the rigid bar and the connecting plates, 120MPa.Please use N as the unit of force to answer, and answers should be rounded to 3 decimal places. (a) Calculate the allowable force P based on tension stress in the steel tube. (7%) (b) Calculate the allowable force P based on shear stress in the rigid bar. (7%) (c) Calculate the allowable force P based on bearing stress between the rigid bar and connecting plates. (7%) (d) Determine the allowable force P for entire system. (4%) | (Hint: calculate (a), (b), and (c) to determine what kind of stress controls in (d).)
