Textbook Question
Chapter 4, Problem 4.1P
and 4.2 Sketch free-body diagram for the members shown.
Expert Solution & Answer
To determine
The free body diagram of the given beam.
Explanation of Solution
Given Information:
Given member is
A free body diagram is a geometrical representation of the different forces acting on a body which are placed for the direct contact points of the body with the arrows showing their implemented direction thereby helping in evaluating the forces that act upon it.
We need to replace the loads with the forces that are there at every point of contact. The concentrated loads will be replaced by single reactions, the fixed cable will also be replaced by single reaction (don’t be confused if it is fixed, as fixed points have to be replaced by three reactions but in this case the beam isn’t directly fixed it is connected with the cable), the pinned by the two reactions and the self-weight with a single reaction.
Free body diagram of the beam.

A 5m-long bar AB is
supported by a ball-in-socket support at A, the cable
CD and a smooth floor at B. A force F = -10 i (N) is
applied at G. Here, D is at the midpoint of the bar AB,
G is the midpoint of AD, and C is the midpoint of OE.
Here, the line BE is parallel to x-axis. Neglect the
weight of bar AB.
Use the scalar method to determine the tension in
cable CD and the reactions at A and B.
(Hint: you can break the tension force by cable DC to
its components.)
