Question
**Robotic Arm Analysis** Consider the robotic arm depicted in the diagram, composed of two arms, AB and BC. Each arm weighs 160 N, with the weight force acting through the midpoint of each arm as indicated. The robotic arm is currently lifting a package weighing 40 N, with this force applied at the center of gravity of the package at the specified location. **Robotic Arm Diagram:** 1. **Diagram Structure:** - The arm is divided into two segments: AB and BC. - Segment AB and segment BC each have a length of 600 mm. - The arm is subjected to forces at various angles: - A force of 160 N acts through the midpoint of each segment. - An additional force of 40 N acts at the end of segment BC. 2. **Angles and Lengths:** - Arm AB makes a 40-degree angle from the horizontal. - Arm BC makes a 20-degree angle from arm AB. - An end segment of 150 mm extends horizontally from arm BC to the load. **Problem Solving:** 1. **Torque Calculation at Point B:** - Determine the torque exerted by a servomotor at point B to counteract the rotation due to the weights of arm BC and the 40 N package. - Calculation should specify the direction of the torque (clockwise or counterclockwise) and report the result in N-m. 2. **Torque Calculation at Point C:** - Determine the torque exerted by a servomotor at point C to resist the rotation due to the 40 N package. - Specify the direction of the torque (clockwise or counterclockwise) and report the result in N-m. 3. **Servomotor Demand Analysis:** - Compare the demand on the three servomotors at points A, B, and C. - Identify which servomotor experiences the largest demand and provide justification for this conclusion. 4. **Load Capacity Enhancement:** - Examine how to adjust the capacity at each servomotor location to allow the robotic arm to lift heavier loads, such as a 140 N package. **Note:** Specific calculations, torque measurements, and mechanical analysis details would be required to complete these tasks, focusing on equilibrium and mechanical advantage principles.
