A meter stick of weight W leans away from a wall. The 0cm line is against the wall at the floor and it makes an angle theta with the wall. It is kept from falling by a horizontal string connected to the 80cm line. What is the tension (T) in the string and what are the horizontal (fx) and vertical (fy) components of force on the 0 cm line?
