    Stress at half of tensile strength

    Ah ok, oops :blushing: forget the term tensile then.Basically, I'm just trying to query on the term 'stress' and how it applies to physical objects. In more basic terms then, (assume all else is relatively equal, joints, leverages, ect etc.) Person A's bicep CSA of 25 with 100 lbs...

    Stress at half of tensile strength

    The larger object has twice the cross sectional area. _____________________________________________________________ Where this debate stems from: It's concerning weightlifting. The details are this: A person is just starting out. Say they are able to curl 50 lbs 10 times and this induces a...

    Stress at half of tensile strength

    Can you guys solve a debate for me? If you have two objects and apply a physical stress to them, let's say in the forum of pressure. First object: Tensile strength 400 lbs. and you apply 200 lbs Second object: Tensile strength 200 lbs and you apply 100 lbs. So each is under 1/2 it's tensile...

    Question on momentum

    I'm not sure, he said "Your using that formula?" Then said I needed to understand calculus for him to explain. The only thing that throws me is he's one of the smartest and most knowledgable people I've ever met, so if we differ, I always assume he's right and I'm wrong. This one just...

    Question on momentum

    Hi Folks, Question on momentum. I have been talking with someone who is more educated than I, especially in math, but they are saying something that just doesn't make sense to me. I do realize that physics doesn't always make 'sense' so thought I'd ask on here. He said I would need...
