    Help Me Find Max Tension/Shear Stress of Object

    Ok I'm going to take another shot at this one. stress = load/area therefore stress = 30,000/.5 so the tension stress is 60,000 psi Am I correct in that the maximum shear stress is equal to one-half of the maximum tensile stress which would make the shear stress 30,000 psi? If I'm right this...

    Calculating Longitudinal Elongation of a Steel Bar | Helpful Tips and Formulas

    Thank you for your help. I think I am understanding now. Stress=force/area therefore stress = 50,000/.25 so the stress is 200,000 psi then using Hooke's law.. strain equals stress divided by modulus of elasticity therefore strain equals 200,000/30,000,000 so strain is .0066667 then to find...

    Calculating Longitudinal Elongation of a Steel Bar | Helpful Tips and Formulas

    Thank you for the warm welcome. I think the fomula needed to find elongation is: Axial tension strain equals change in length divided by original length I know that the original length is 100 ft, but I still need to find the stain in order to complete the problem. I think this...

    Help Me Find Max Tension/Shear Stress of Object

    Does this mean that I can use any variable for length of the cross section since I am not specifically given one? Such as if I used 12in for the length I could determine the area of the object would be (12x2) + (12x2) + (.25x12) + (.25x12) = 54 sqin Which would then be used in the formula...

    Help Me Find Max Tension/Shear Stress of Object

    Hello, I am hoping that someone can help to point me in the right direction to solving the following problem. I need to find the max tension stress and max shear stress of the object shown in the attachment and then compare those stresses with the ultimate tension stress of 64,000 psi and...
