Could you just give me some assistance on part b please.  Thanks.

**Mastering Engineering: Truss Analysis** --- **Assignment 14 - Problem 6.46** *Consider the truss shown in (Figure 1). Suppose that \( F = 11 \, \text{kN} \).* --- **Part A** Calculate the force in member \( EF \) of the truss. Include three significant figures and appropriate units. Use a positive value for tension and a negative value for compression. - **Answer:** \( F_{EF} = 13.0 \, \text{kN} \) - Status: **Correct** --- **Part B** Determine the force in member \( CH \) of the truss and state if the member is in tension or compression. Include three significant figures and appropriate units. Use a positive value for tension and a negative value for compression. - **Input field for answer with units** - **Status:** Incorrect; Try Again. Two attempts remaining. --- **Part C** Calculate the force in member \( GH \) of the truss. Include three significant figures and appropriate units. Use a positive value for tension and a negative value for compression. --- **Figure Description** The figure displays a truss structure comprising multiple members connected at joints. Key points and forces are identified: - **Dimensions:** Horizontal members are uniformly 4 meters apart, creating repetitive triangular sections. - **Loads:** External forces are applied at specific points: - \( A \) to \( B \): 4 kN - \( D \): 11 kN - \( F \): 5 kN - **Components:** Different sections of the truss are labeled with nodes from \( A \) to \( I \). Understanding and analyzing this truss helps in determining the internal forces, providing insight into its structural integrity. --- **Note:** Use the provided figure to assist in visualizing member connections and force distributions during your calculations.
