(a) In Fig. 11.46a6.00-mlong, 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-N weight is bung; an unknown weight w bangs at 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 is w?
