I've noticed that alot of the people on this forum are extremely intelligent and would probably be fairly good at physics. I was away from school for a few days and missed some physics questions and my teacher gave me some questions to do but forgot to give me the answers. So if someone or some people could do these questions (and show work if you want) to see if I got the same answers it would really help me out.
1. A non-uniform beam with a mass of 85kg has a length of 6.2m and is attached to a wall and supported at an angle of 28 degrees from the wall by a horizontal rope which is attached to the wall above the beam . The tension in the rope is found to be 310N. How far from the pivot point is the center of mass of the beam? The diagram looks like this: 89az6.png
2. A uniform diving board is 4.5m long, it's mass is 45kg. A person with a mass of 75kg stands at the end. Support A holds the board at the other end support B is 1.0m away from support A. Calculate the magnitude and direction of the forces support A and B exert.
This diagram looks like this: 89b8U.png
I know this is a little out of the ordinary but hell it's worth a shot. Hopefully someone knows the answer.
