# Homework Help: Tension and Static Friction

1. May 12, 2010

1. The problem statement, all variables and given/known data
There is a 40 newton beam being held by a rope. The rope is attached at the top of the beam and the ground making a 25 degree angle at the top of the beam. There is a force applied to the beam with 200 newtons in the positive x direction. Find the tension and static friction.

All I think I have figured out is:

Ftoty = T(cos 25) - 200

T = 200
cos 25

T = 220.676N

Ftotx = 200N - Fs - Tsin 25

Fs = 200N - (220.676 sin 25)

Fs = 106.738

Not sure if this is correct.

No it's like this.

Where is the 200 N force applied? Halfway up the vertical member??

It does not state where it's applied. I'm guessing center of gravity?

The 200 N force is apparently an applied horizontal force....have you stated the problem correctly? Does the vertical member only weigh 40 N? Something is not right....
