The pipe assembly is fixed at A. The rod has a diameter of 25 mm and made of A-36 steel. Please answer the following questions: Question 1: Please, determine the state of stress at point E on the cross section of the rod at section a-a. (25P) Question 2: Please, determine and draw the principal stress and maximum in- plane shear stress at Point E on the cross section of the pipe at section a-a. (15P) Question 3: Please determine the total elastic strain energy that can be stored in the rod A-B. The distance between A-B is 400 mm. Neglect the shearing strain energy. (20P) Question 4: Please, determine the factor of safety for the above given material for all applicable theory. (20P) 300 mm a B 250 mm C Section a-a D 200 mm 450 N 550 N Question 5: What diameter should be used for the shaft (A-B) in order to get a factor of safety 10, if the rod A-B is to be made of Cast Iron Alloys -ASTM A-197. Consider please for this calculation only an axial tension force of 55 kN applied on the A-B member. (20P) P
