---**Problem 2: Force Analysis on a Bent Bar ABC****Problem Statement:**A bent bar ABC is supported and subjected to forces as depicted in the diagram. Determine the reactions at points A, B, and C, assuming negligible friction and bar weight.**Diagram Description:**The provided diagram illustrates the bent bar ABC, consisting of two segments joined at point B:- The horizontal segment AB, which is 10 feet long (5 feet from A to B).- The inclined segment BC, which forms an angle of 45° with a horizontal smooth slot and is 6 feet long (3 feet from B to C).The bar is supported by:- A horizontal smooth slot at point A.- A pinned connection at point B.- A vertical smooth slot at point C, inclined at an angle of 45° to the horizontal.The forces acting on the bar are:- A vertical downward force of 200 N at point A.- A 300 N force acting vertically downward on point C.**Diagram Explanation:**1. **Point A:** - A smooth horizontal slot supports this point, allowing only vertical movement. Therefore, the reaction at A (R_A) is a vertical force. 2. **Point B:** - This point features a pinned connection, which can support forces in both the horizontal and vertical directions, denoted as \( B_x \) for the horizontal component and \( B_y \) for the vertical component.3. **Point C:** - The smooth slot here is inclined at 45°, indicating that it can exert an equal reaction force component in both the horizontal and vertical directions. This reaction force can be decomposed into \( C_x \) and \( C_y \).---**Analysis Approach:**1. **Static Equilibrium Equations:** - Sum of forces in the horizontal direction (ΣF_x = 0) - Sum of forces in the vertical direction (ΣF_y = 0) - Sum of moments about point B (ΣM_B = 0)2. **Force Components:** - The inclined reaction at C results in components: - \( C_x = C \cos(45°) \) - \( C_y = C \sin(45°) \) - Given \( \cos(45°) = \sin(45°) = \frac{1}{\sqrt{2}}
