Chapter 11, Problem 11.60P

(a) In Fig. P11.60 a 6.00-m-loog, uniform beam is hanging from a point 1.00 m to the right of its center. The beam weighs 140 N and makes an angle of 30.0° with the vertical. At the right hand end of the beam a 100.0-N weight is hung; an un-known weight w hangs is the left end. If the system is in equilibrium, what is w? You can ignore the thickness of the beam, (b) If the beam makes, instead an angle of 45.0° with the vertical, what it w?
