Torque and Equilibrium of a Rod

AI Thread Summary
To determine if pulling the left end of a pivoting rod can cause the right end to push down, one must analyze the conditions for equilibrium, specifically that both the net force and net torque must equal zero. When pulling on the left end, the force creates a torque about the pivot point, which can indeed result in the right end pushing down if the applied force is sufficient to overcome the rod's weight and any opposing forces. The direction of the pull should be downward and towards the pivot to maximize torque. Understanding the relationship between force, torque, and equilibrium is crucial in solving this problem. The discussion emphasizes the need for a clear grasp of these physics concepts to approach the solution effectively.

Homework Statement



Here's a diagram of a rod that's free to pivot about the point indicated. Is it possible to make the right end of the rod push down, by pulling on the left end of the rod? If so, show on the diagram the direction that you would pull on the left end of the rod, and explain your reasoning. If not, explain why not.

Please see my attachment for the rod diagram.

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
