3 When a 20-N weight is placed on the end of the uniform loating wooden beam in Fig. P2.133, the beam tilts at an angle 0 with its upper right corner at the surface, as shown. Determine (a) the angle 0 and (b) the specific gravity of the wood. Hint: Both the vertical forces and the moments about the beam centroid must be balanced. 20 N Water 2.7 m 10 cm x 10 cm
