### Structural Mechanics ProblemThe image illustrates a statics problem involving a sign connected to a wall. The setup includes the following components:- A sign labeled as \( ABCD \).- A support member \( BE \).- The sign is connected to the wall by a pin at \( A \) and supported by the member \( BE \).#### ObjectiveDetermine the reaction forces at points \( A \) and \( E \). Enter your answers in Cartesian components. The weights of both the sign \( ABCD \) and member \( BE \) should be accounted for in the calculation. Assume the pins are located a distance \(\frac{w}{2}\) cm from the ends at each connection.#### Diagram ExplanationThe diagram indicates:- Dimensions between points and width (\( w \)): - \( AB = a \) - \( BC = b \) - \( AE = c \) - Vertical drop from \( B \) to \( D = h \)- There are horizontal and vertical forces acting due to the connection at \( A \).- The reaction forces need to be calculated at \( A \) and \( E \).#### Dimension ValuesThe values for dimensions indicated in the figure are:| Variable | Value ||----------|--------|| \( a \) | 2.90 m || \( b \) | 3.77 m || \( c \) | 2.18 m || \( h \) | 3.02 m || \( w \) | 9.50 cm |#### Calculation Prompts- The reaction at \( A \) is \(\vec{A} = 0 \, \hat{i} + 0 \, \hat{j} \, \text{N}\).- Determine the reaction at \( E \), express as \(\vec{E} = \text{(input)} \, \hat{i} + \text{(input)} \, \hat{j} \, \text{N}\).Overall, this problem requires applying principles of statics to calculate the reaction forces using the specified dimensions and given conditions. ### Problem DescriptionA sign \( ABCD \) is constructed from 7 mm thick plate steel (density \( \rho = 8000 \, \text{kg/m}^3 \)) with the geometry shown in the figure. The sign is connected to the wall by a pin at \( A \) and also supported by member \( BE \). Support member \( BE \) is also constructed from 7 mm thick plate steel and is connected by pins at \( B \) and \( E \) respectively. Determine the reaction forces at \( A \) and \( E \). Enter your answers in Cartesian components. The weights of both the sign \( ABCD \) and member \( BE \) should be accounted for in the calculation. Assume the pins are located a distance \( \frac{w}{2} \, \text{cm} \) away from the ends at each connection.### Diagram DescriptionThe diagram includes:- A rectangular sign connected to the wall at \( A \).- The sign extends horizontally to point \( D \).- Support member \( BE \) connects to the wall with a vertical section at \( E \) and joins the sign at \( B \).- Dimensions are marked for various sections including \( a \), \( b \), \( c \), \( h \), and \( w \).### DimensionsThe following variables and their values are given:- \( a = 2.90 \, \text{m} \)- \( b = 3.77 \, \text{m} \)- \( c = 2.18 \, \text{m} \)- \( h = 3.02 \, \text{m} \)- \( w = 9.50 \, \text{cm} \)### EquationsThe reaction at \( A \) is:\[ \vec{A} = 0 \, \hat{i} + 0 \, \hat{j} \, \text{N} \]The reaction at \( E \) is:\[ \vec{E} = \, \hat{i} + \, \hat{j} \, \text{N} \]Fill in the calculated values for \( \vec{E} \) with the appropriate units.
