Chapter 1, Problem 1.12(choose chapter or problem)
The frame shown consists of four wooden members, ABC, DEF, BE, and CF. Knowing that each member has a \(2 \times 4 \text {-in. }\) rectangular cross section and that each pin has a \(\frac{1}{2} \text {-in. }\) diameter, determine the maximum value of the average normal stress (a) in member BE, (b) in member CF.

QUESTION:
The frame shown consists of four wooden members, ABC, DEF, BE, and CF. Knowing that each member has a \(2 \times 4 \text {-in. }\) rectangular cross section and that each pin has a \(\frac{1}{2} \text {-in. }\) diameter, determine the maximum value of the average normal stress (a) in member BE, (b) in member CF.
ANSWER:
Step 1 of 9
In the given problem we have to find the normal stress in members BE and CF. Cross-sectional areas of each member are given to us. We will first estimate the support reactions at point D and then consider the equilibrium of part DEF to estimate axial forces in members BE and CF.
