2) A cantilevered truss is loaded as shown below. Using method of sections determine the force in member BC. Leave your answer in terms of P. Specify tension (T) or compression (C). (FYI, you do not need a calculator to do this problem.) (Hint: you do not need to find the support reactions to do this problem.) Ans: FBC = (9P)/4 (T) 6 m 6 m 4 m D E 3 m 6 m 3 m

**Problem Statement:** 2) A cantilevered truss is loaded as shown below. Using the method of sections, determine the force in member BC. Leave your answer in terms of P. Specify tension (T) or compression (C). (FYI, you do not need a calculator to do this problem.) (Hint: you do not need to find the support reactions to do this problem.) **Answer:** \[ F_{BC} = \frac{(9P)}{4} \, (T) \] **Diagram Explanation:** The diagram shows a cantilevered truss with the following configuration: - The truss has three main points labeled A, B, and C in a horizontal line, each 6 meters apart. - A force \(P\) is applied downward at point A. - Points D and E form a triangular formation below AB and BC. - The vertical member AE is 4 meters long, and DE is 6 meters long at the base of the triangle. - Member BC is the section of interest to find the force using the method of sections. - Member AE is perpendicular to AC with a horizontal distance of 3 meters from D to E. The problem involves analyzing the internal forces in the structural system, specifically in member BC, and determining if this member is in tension or compression.
