    Rotational Loading Homework: Find Force Pulling Arm away from Pivot Point

    Hey thanks for the help. Hmm when I'm checking the units (SI) something's not adding up quite right. Is it as simple as substituting in the rpm speed (which is technically a frequency) with the rule omega=2*pi*f? The rads/sec doesn't seem to cancel out and I'm not left with Nm for the units of...

    Rotational Loading Homework: Find Force Pulling Arm away from Pivot Point

    Sorry I may have overshot the mark of my original question. Attached is what I think I am understanding, am I on the right path? This will allow me to test the difference that increases in the Mass M have on the torque applied at point A. Is it possible for you to show me how you derived the...

    Rotational Loading Homework: Find Force Pulling Arm away from Pivot Point

    I'm sitting here at the moment: T(A) =M*omega(A)^2*r1*r2 (as you said) where omega(A)=v^2(A)/r1 then T(A)=M((V(r1)^2)/r1)^2*r1*r2 - equation 1 So to convert something like rpm to get a velocity (as V would be the unknown), V=circumference of travel * rpm = pi*d*rpm So if I find V at point A...

    Rotational Loading Homework: Find Force Pulling Arm away from Pivot Point

    Hi Thanks for the reply. So I'm not trying to find a torque at the mass M, but actually a torque at point A? I guess that makes sense. I imagine you're talking about centripetal acceleration? Is that the same as centrifugal? So all I'd need to do is find: A(R1) = V(R1)^2/R1 This is not...

    Rotational Loading Homework: Find Force Pulling Arm away from Pivot Point

    Homework Statement I'm not using numbers because I only want to understand the mathematical relationship. This is not a coursework question, but I imagine it stems from coursework level physics. I am trying to design a rotating arm for my own use and I want to calculate bracing requirements...
