This system contains points A, B, and C, along with a point G located at the center of the bottom linkage. Here are the details of the setup:1. **Point A**: Positioned at the base of the system, on the horizontal line.2. **Point B**: The joint connecting the bottom linkage to the right vertical line.3. **Point C**: The joint connecting the upper rod to the vertical line above point B.4. **Point G**: A marked point located at the center of the bottom linkage between A and B.#### MeasurementsMeasurements are provided to give dimensions to the configuration:1. The horizontal distance from point A to the right vertical line, measured along the ground, is **4 feet**.2. The vertical height from point B to point C is **1.5 feet**.3. The total vertical distance from the ground to point B is **3 feet**.#### Practical ApplicationsThis type of configuration is typical in various mechanical and structural applications. Some practical aspects include:- **Lever Systems**: The points A and B can be used to demonstrate principles of leverage.- **Static Equilibrium**: By analyzing forces at these points, one can study equilibrium conditions.- **Linkage Mechanisms**: Useful in illustrating basic principles of linkages used in machinery and robotics.#### SummaryUnderstanding configurations like this one is essential in studying mechanical and civil engineering principles. The distances and measurements provided enable precise calculation and analysis, making it an excellent educational example. ### Bar/Rollers/Wire System ProblemExplore the mechanics of a Bar/Rollers/Wire system as depicted. The system consists of a bar and rollers assembly weighing 60 lbs, with its center of mass (G) located at the midpoint of Bar AB. Wheels at points A and B rest on frictionless horizontal and vertical surfaces, respectively.#### Instructions:1. **Drawing the Free Body Diagram (FBD):** - Draw the FBD of the Bar AB assembly, including the rollers at points A and B. - Create a separate diagram and do not use the provided figure. **FBD Requirements:** - Clearly and correctly indicate the reaction forces at points A and B. - Show the weight force and the tension force \( T \) in the wire. - Define positive "x" and "y" directions. - Include all necessary dimensions and angles for computing moments and force components.2. **Equilibrium Equations and Force Calculation:** - Write the equilibrium equations to find the reaction forces at points A and B. - Calculate the tension force \( T \) in the wire. - Clearly present results considering the direction in which the reactions act on the body. - Express all forces in lbs.This educational exercise involves understanding the principles of static equilibrium, the interaction of forces, and the mechanics of engineering structures. This task will help in sharpening problem-solving skills while applying theoretical knowledge to practical scenarios.### Explanation of Concepts- **Free Body Diagram (FBD):** A graphical representation used to show all the forces acting on a single body. It is crucial for solving problems in mechanics.- **Equilibrium Equations:** Mathematical expressions derived from Newton's First Law, stating that a body at rest or moving at constant velocity has zero net force and zero net moment. \( \sum F_x = 0 \) \( \sum F_y = 0 \) \( \sum M_z = 0 \) - **Reaction Forces:** Forces that occur at the points of contact between surfaces. These are perpendicular to the contacted surfaces if friction is negligible.- **Tension Force:** A force transmitted through a string, cable, or wire when it is pulled tight by forces acting from opposite ends.- **Weight (W):** The force due to gravity acting on the mass of the bar, calculated as \( W = mg \).

Consider the Bar/Rollers/Wire system of the figure. The Bar and Rollers assembly weighs 60 lbs, with center-of-mass at point G, located at the midpoint of Bar AB. The wheels at points A and B rest on frictionless horizontal and vertical surfaces, respectively.. 1. Draw the FBD of the Bar AB assembly together with the rollers (points A and B). You must draw a separate diagram and you may NOT use the existing figure given here. Your FBD must clearly/correctly show the reaction forces at points A and B, in addition to the weight and the tension force T in the wire. The FBD should define the positive “x" and “y" directions, and include the dimensions and/or angles necessary for computing moments and force components. 2. Write the equations of equilibrium and solve to find the reaction forces acting at Points A and B. In addition, find the tension force T in the wire. You must be clear in your results with respect to the direction in which the reactions act on the body. Express forces in lbs.
