A 20-ft wrought iron bar that is ½ inch in diameter is subjected to a tensile force of 3 kips. Determine the a) stress in psi, b) elongation of the bar in inches, and c) strain. The modulus of elasticity of wrought iron E = 29 x 103 ksi.

Problem 6

Sketch the stress-strain curve and explain it in relation to the tensile test for steel bars.

PLEASE WRITE YOUR COMPLETE SOLUTION AND BOX THE FINAL ANSWER. THANK YOU. A series of rigidly attached aluminum bars carries the axial loads at the positions shown. If the modulus of elasticity E = 16×10^6 psi, compute the total deformation of the bar and state if the bar elongates or shortens. Assume that the bar is suitably braced to prevent lateral buckling.

Can I get a walkthrough for this problem?

Please help

asap please thank you
