For the design of the bar force members at AE, BC, and BE, calculate the steel's gross area. The stress in steel is given as A36 = 36 ksi. 400 lb 300 lb 15 ft 25 ft 15 ft 50 Ib 30 ft A

A steel bolt has a diameter of 8 mm. The bolt is encased by a bronze tube that has an outer diameter of 15 mm and inner diameter of 8 mm. A force is applied to the bolt. F d3 d1 F Values for the figure are given in the following table. Note the figure may not be to scale. Variable Value F₁ 25 kN Esteel 200 GPa Ebronze 105 GPa a. Determine the magnitude of the normal force in the steel bolt, Nsteel. b. Determine the magnitude of the normal force in the bronze tube, Nbronze. c. Determine the magnitude of the normal stress in the steel bolt, σsteel. d. Determine the magnitude of the normal stress in the bronze tube, σbronze Round your final answers to 3 significant digits. Nsteel = KN Nbronze = KN σ steel = MPa MPa Obronze

A pipe with an inside diameter of 42 mm is subjected to an axial load of 850 kN. If the maximum allowable tensile stress in the pipe is 2.50 kN/mm², calculate the minimum wall thickness required for the pipe. Give your answer in millimetres (mm) to 2 decimal places.

Rank the normal stress in each section of the bar. Rank the values of normal stress from largest (largest tensile stress) to smallest (largest compressive stress). Use AB for segment AB, BC for segment BC, and CD for segment CD.

Kindly show the complete step-by-step solution and free body diagram. Please make sure that your handwriting is understandable and the picture of the solution is clear. This topic is about "Normal/Axial Stress" I will rate you with “like/upvote” after. I need the answer right away, thank you.
