SolveSample Problem 4.1.All remain as presented, except for the following changes.The factor ofsafety is now 2, and not 3.As Presented, the thickness of the tube is uniform. In the new one that you are solving,let the thicknessesof the top and bottom be the same,ttb, and the thicknesses of theleft and right be the same,tlr.Theheightand the width of the tube are still respectively 5 in and 3.25 in.As you make thesethickness changes,you are to keep thetotal mass of the tube unchanged. Answer the same questions (a) and (b).Explain your findings
QUESTION 4 4.2 4.1 The ratio between the outside diameter and inside diameter of a pipe is 2,5 and the length is 400 mm, when the pipe is not subjected to any load. When a tensile load of 200 kN is applied to the pipe, its length increases by 0,195 mm. The Young's modulus of elasticity for a pipe is 188 GPa. Calculate the inside diameter and outside diameter of a pipe. The following results were obtained by means of a tensile test on a carbon steel specimen, having an original cross-sectional area of 20 mm² and the gauge length is 50 mm. Elastic limit load: Elongation at the elastic limit: =0,06125 mm =4 900 N Maximum load: =7 650 N Load at fracture: =5 050 N Elongation at failure: =15,2 mm Cross-section area at failure: 7,95 mm² Calculate the following: 4.2.1 The stress at the elastic limit. 4.2.2 The maximum stress. 4.2.3 The percentage elongation. 4.2.4 The percentage reduction in area.
What is the cross sectional area necessary to carry a 50 ton force (tensile load) in a square bar with a tensile strength of 80000 ibs/sq in?
