Okay, but doesn't this assumption already imply the conclusion, which is that at any point the torque is zero? We don't know if ##\tau=Fx^2## or ##Fe^x## but it seems like (2.8) is still trying to say the net torque is zero, because he sets them equal to each other. It seems like the first...
Ok, this response mostly makes sense to me, except that equation 2.8 is reasonable. (2.8) can be rearranged to exactly say that ##F_3f(a)-F_2f(a+b)=0##, which implies already that the torque is zero, although we are still trying to investigate what f(x) is it still seems to imply that. Why can't...
Homework Statement
All context is given here. I am trying to understand a few things about what Morin is doing.
1) How is proving that f(x) is a linear function, which I understand the proof of, relevant to the claim that the torques at the left end cancel? Also, the introduction of the...
