Question on wire tension & hinge force

AI Thread Summary
The discussion centers on a physics problem involving a 55 kg person standing on a 5.65 m beam with a mass of 40 kg, supported by a wire at a 30-degree angle. The goal is to calculate the hinge force components (Rx and Ry) and the tension (T) in the wire. Participants note that this type of question is typically suited for a homework help forum. It is suggested that the original poster repost their inquiry in the appropriate section for better assistance. The conversation emphasizes the importance of using the correct forum for specific types of questions.

A person with mass 55.0 kg stands d = 1.85 m away from the wall on a x = 5.65 m beam. The mass of the beam is 40.0 kg. A wire connects the end of the beam to the opposite wall at an upward 30 degree angle. Find the hinge force components (Rx and Ry) and the tension (T) in the wire.

btw, the wall that the wire connects to is facing opposite the first wall which is connected to the beam.
 
This sounds like you're asking for help on a homework problem. There is a separate forum for homework help. You might want to repost this there.
 
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...
