Physics Multiple Choice: Torque Direction

AI Thread Summary
The discussion focuses on determining the direction of torque using the right-hand rule. The original poster suggests that the torque direction is "out of the page," based on their application of the rule. However, they express uncertainty and reconsider whether it could be "into the page." Participants discuss the relationship between force and lever arm direction, emphasizing the importance of correctly applying the right-hand rule for accurate torque direction. The conversation highlights the common confusion surrounding torque direction in physics problems.

The Attempt at a Solution



I said out of the page because when I use the right hand rule, my thumb points outwards but what do you guys say?
 
Physics news on Phys.org
It might be inwards now that I try it again
 
Wow I already seen that.

Force is up and Lever arm is up.
 

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
