Newton’s law of motion for rotation clarification

AI Thread Summary
The discussion revolves around clarifying the values of Beta and Tmax in the context of Newton's laws of motion for rotation. Tmax is identified as the maximum thrust from each motor, set at 8N. Participants suggest using the relationship from Newton's second law for rotation, Torque = I*alpha, to deduce Beta, which is calculated as approximately 888.889. There is also a query about the total thrust needed to maintain height and the value of 'd' being used. The equation mentioned is intended to solve for the variable t1.

Hey guys,
I'm trying to work through a question but the solution we have been given is extremely vague. I can't seem to figure out what any of the values such as Beta or Tmax are. If I knew how to work those two out, I'm sure I'd be fine from there...

See attached image.

Thanks in advance

It looks like T is the thrust from each motor, so ##T_{max}## would be the maximum thrust. And from Newton's 2nd law for rotation, Torque = I*alpha, you should be able to deduce what Beta is.
 
Well seeing as T1 is Tmax...(8N) I get Beta as 888.889...Not sure if it means both T1 and T2. Also what would be the value of t in the second equation at the bottom?

Careful. What must the total thrust be so as to maintain the height? Also, what value of d are you using?

The purpose of that equation is to solve for ##t_1##.
 

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...
