**Example Problems on Beam Reactions** --- **Problem 4-82:** Determine the reactions at points A and B for the frame illustrated in Figure P4-82. *Figure P4-82 Description:* The frame consists of a structure with a triangular configuration. Point C is at the base on the left side, forming a 30° angle with the horizontal ground. There's a 1800 lb force acting vertically downward at point C. A horizontal member is connected at point C and extends 10 ft to the right, where it meets point A which is positioned slightly above the horizontal member by 0.5 ft. From point A, another member extends downwards at an angle and meets point B, located 6 ft to the right of C and below point A. The end support at point B is fixed. --- **Problem 4-83:** Determine the reactions at point A for the beam shown in Figure P4-83. *Figure P4-83 Description:* The beam structure shown has a vertical beam segment of 15 ft on the left side and a horizontal segment extending 4 ft to the right. From the top end of the vertical segment, another segment extends at a 45° angle upwards to the right, connecting back to the vertical segment 8 ft above the ground. A 300 lb force acts downwards at a point located 5 ft to the right from the point where the angled segment meets the vertical one. The beam supports are positioned on the ground at both ends of the 4 ft horizontal segment. --- *Note: These diagrams involve structural elements and applied loads essential for solving reaction forces in these beam structures. The analysis typically involves methods of static equilibrium to find the reactions at the specified points, including summing forces and moments and solving the resulting equations.* *Educational Objective: Understanding how to determine reaction forces in beam structures using principles of static equilibrium.* Page: 151
