Problem 2
The cylindrical plate is subjected to the three cable forces which are
concurrent at point D. Express each force which the cables exert on
the plate as a Cartesian vector, and determine the magnitude and
coordinate direction angles of the resultant force.

Problem 8
The wooden plank resting between the buildings deflects slightly
when it supports the 50-kg boy. This deflection causes a triangular
distribution of load at its ends, having maximum intensities of wa and
wb . Determine wa and wb , each measured in N/m, when the boy is
standing 3 m from one end as shown. Neglect the mass of the plank.
