A cable is attached to the end of the rod and to a point on the wall at distance \( d_v \) above the point where the rod is hinged to the wall. (a) What is the tension in the cable?(b) What is the horizontal component of the force on the rod from the wall? Take the positive direction to be to the right.(c) What is the vertical component of this force? Take the positive direction to be upward. State your answer in terms of the given variables, using \( g \) when appropriate.#### Diagram Analysis:The provided diagram illustrates the setup as follows:- A sign labeled "H. Perez DENTIST" is a square with edge length \( L \).- The sign hangs on a rod that extends horizontally from a wall.- The rod is hinged at the wall, and its length is \( d_h \).- A cable supports the rod by connecting from the end of the rod to a point \( d_v \) above the hinge point on the wall.- The forces on the system include the tension in the cable and the reaction forces at the hinge (horizontal and vertical components).#### Solutions:(a) **Tension in the Cable:**The expression provided for the tension in the cable is:\[ \text{Tension} = \tanh\left(\frac{d_v}{d_h}\right) \](b) **Horizontal Component of the Force on the Rod from the Wall:**The provided expression for the horizontal component is:\[ \text{Horizontal Force} = \tanh \left(\frac{d_v}{d_h}\right) \](c) **Vertical Component of the Force from the Wall:**An examination of the image does not indicate an explicit expression for part (c), but the forces will involve gravitational effects through the use of \( g \), the gravitational constant, and the weights of the rod and sign.#### Detailed Diagram Explanation:- The diagram includes labeled lengths: \( L \), \( d_h \), and \( d_v \), which correspond to the square sign's edge length, the horizontal distance from the wall to the end of the rod, and the vertical distance from the hinge point to where ### Educational Content on Structural Mechanics#### Diagram DescriptionThe diagram represents a structural setup involving a sign hanging from a hinge and supported by a rod and a cable. Key components and dimensions in the setup include:- **Hinge:** This is the point where the sign is attached to the supporting structure (wall).- **Rod:** A horizontal element connected to the sign providing support.- **Cable:** An inclined element providing additional support from the top of the wall to the end of the rod.- **Sign:** A sign labeled "H. Perez DENTIST" hanging from the hinge.- **Dimensions (L, dv, dh):** Various distances and lengths are indicated in the diagram: - \( L \): Length from the hinge to the right end of the sign. - \( d_v \): Vertical distance from the hinge to the point where the cable is attached at the top of the wall. - \( d_h \): Horizontal distance from the hinge to the left side of the sign.#### Mathematical ExpressionsSeveral mathematical expressions are provided to describe forces and moments acting on the system:1. **Expression (a):** \[ \tanh\left(\frac{dv}{dh}\right) \] This expression utilizes the hyperbolic tangent function to model the ratio of vertical to horizontal distances.2. **Expression (b):** \[ T \cos(\theta) \] This expression describes the horizontal component of the tension force \( T \) in the cable, where \( \theta \) is the angle between the cable and the horizontal axis.3. **Expression (c):** \[ \frac{mg \left( 2h - d_h \right)}{2h} \] This expression calculates a force or moment involving the mass \( m \) of the sign, gravitational acceleration \( g \), and dimensions \( h \) and \( d_h \).### Explanation of the Diagram and FormulasThe diagram represents a practical problem in structural mechanics where equilibrium conditions must be satisfied for the sign to remain stable. The rod and cable work together to balance the forces and moments generated by the sign's weight. The mentioned expressions can be used to analyze and solve for unknown variables such as tension \( T \), angles, and forces ensuring the stability of the setup.#### Practical ApplicationThis type of analysis is fundamental in civil engineering and structural design
