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.
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
