DISCUSSION<\/strong><\/em><\/span>
\nUsing the four-step plan:
\n
\nSTEP 1<\/strong><\/em>: Free body diagram (FBD)<\/strong><\/em> – Draw an FBD of bar AB.
\n
\nSTEP 2<\/strong><\/em>: Kinetics<\/strong><\/em> – Write down the Newton\/Euler equations for the bar based on your FBD above. For the “short form” of the Euler equation, please note that you are constrained to using a moment about the center of mass G since there are no fixed points on AB; that is, you should use \u03a3M<\/strong><\/em>G<\/sub> = IG<\/sub> \u03b1<\/strong><\/em>.
\n
\nSTEP 3<\/strong><\/em>: Kinematics<\/strong><\/em> – With the inextensible cable being taut, all points on the rigid body AB have the same acceleration, and the angular acceleration of AB is zero: \u03b1<\/strong><\/em> = 0<\/strong><\/em>.
\n
\nSTEP 4: Solve<\/strong><\/em> – Use the equations from STEPS 2 and 3 to solve for the tension in the cable and the reaction at on the bar at A.<\/p>\n
