Representing the Weight of an L-Shaped Bar
The mass of the homogeneous slender bar in Fig. 7.33 is 80 kg. What are the reactions at A and B?
Strategy
We determine the reactions in two ways.
First Method We represent the weight of each straight segment of the bar by a force acting at the center of mass of the segment.
Second Method We determine the center of mass of the bar by determining the centroid of its axis and represent the weight of the bar by a single force acting at the center of mass.
