The frame supports the distributed load shown. Determine the state of stress acting at point \( E \). (Figure 1) ### Figure The diagram illustrates a frame subjected to a distributed load of 4 kN/m. The frame is supported at point \( A \) and has a triangular shape with dimensions marked as \( 1.5 \, \text{m} \) from \( A \) to \( D \) and \( 3 \, \text{m} \) from \( D \) to \( B \). The section \( BC \) is inclined, with \( B \) to \( C \) measured at \( 5 \, \text{m} \) and horizontally covering \( 3 \, \text{m} \) from \( B \) to \( C \). At point \( E \) (located below point \( D \)), the vertical dimensions are marked as 20 mm, 60 mm, and 20 mm, resulting in a total height of 100 mm. The entire width of the section at point \( E \) is 50 mm. ### Part A **Determine the normal tensile stress at point \( E \).** *Express your answer using three significant figures and include the appropriate units.* \( \sigma_E = \, \text{Value} \, \text{Units} \) [Submit | Request Answer] ### Part B **Determine the shear stress at point \( E \).** *Express your answer using three significant figures and include the appropriate units.* \( \tau_E = \, \text{Value} \, \text{Units} \) [Submit | Request Answer]
