Question
Gripper \( C \) of the industrial robot is accidentally subjected to the \( F = 63 \, \text{lb} \) side load, directed perpendicular to \( BC \). The lengths of the robot's links are \( AB = 24 \, \text{in.} \) and \( BC = 18 \, \text{in.} \). By using the moment components method, determine the moment of this force about the center of joint \( A \). (Express your answer using three significant figures.) \[ M_A = \text{____} \, \text{ft} \cdot \text{lb} \] **[Dropdown for unit selection]** --- **Diagram Description:** The diagram shows an industrial robot arm with joints labeled \( A \), \( B \), and \( C \). The arm consists of two segments: \( AB \) and \( BC \). Segment \( AB \) is \( 24 \) inches long, and segment \( BC \) is \( 18 \) inches long. There is a force \( F = 63 \, \text{lb} \) applied at point \( C \), perpendicular to segment \( BC \). - \( \angle ABC = 40^\circ \) - \( \angle BAC = 15^\circ \) The coordinate system is depicted, with \( x \) and \( y \) axes, indicating the orientation of the robot arm.
