Question
In the figure, \( L = 10 \), \( P_1 = 750 \, \text{lb} \), and \( P_2 = 620 \, \text{lb} \). Compute the member forces listed below. In each case, tension is positive and compression is negative. [Hint: To find the distance from \( A \) to \( B \), you could use the law of sines in triangle \( ABF \). Or, you could first find the distance from \( C \) to \( B \) in the triangle \( BCE \), which has a right angle at \( C \).] **Diagram Explanation:** The diagram illustrates a truss structure with various forces and angles labeled. The structure is symmetric with the following details: - **Points**: A, B, C, D, E, and F indicate key joint locations within the structure. - **Forces**: - \( P_1 \) acts downward at point \( C \). - \( P_2 \) acts horizontally to the left at point \( B \). - **Members**: - The truss consists of several members forming triangles such as \( ABF \), \( CBF \), and \( CDF \). - **Angles**: - Two 60° angles are formed between the horizontal beam and members \( BF \) and \( DF \), and a 30° angle between the same beam and members \( BE \) and \( DE \). - **Measurements**: - Each horizontal section of the truss measures \( L \) feet.
