SUMMARY
The displacement of point D in a compound bar consisting of a steel bar and a brass bar, both with a diameter of 36 mm, is calculated using the formula PL/AE. Given the forces PB=54 kN and PD=117 kN at points B and D respectively, the correct application of these forces is crucial for accurate displacement determination. The discussion emphasizes the importance of showing work to receive assistance, highlighting the collaborative nature of problem-solving in engineering contexts.
