Static Equilibrium: Net Force & Torque = 0

AI Thread Summary
The discussion centers on understanding the concept of static equilibrium, specifically regarding net force and torque being equal to zero. The term "minimum" refers to the maximum distance a person can stand on a board before the left support experiences zero normal force, effectively turning the board into a seesaw. Participants clarify that this situation involves determining the balance point where the forces shift. The focus is on the conditions that lead to a loss of reaction at one support. Understanding these principles is crucial for solving related physics problems.

Net Force = 0
Net Torque = 0

The Attempt at a Solution


I know how to deal with these problems. My question is: What the word 'minimum' means here? A zero normal force over the second support point?

It means, how far to the right of the right support can the boy stand before there is zero reaction at the left support. IOW, when will the board become as see-saw?
 

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'

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...
