Question

A 3.5-kg slender rod AB and a 2-kg slender rod BC are connected by a pin at Band by the cord AC. The assembly can rotate in a vertical plane under the combined effect of gravity and a couple M applied to rod BC. In the position shown, the angular velocity of the assembly is zero and the tension in cord AC is equal to 271 N. 400 mm 400 mm 300 mm A Problem 16.090.a - Rotation about a fixed point: Equations of motion Determine the angular acceleration of the assembly. (You must provide an answer before moving to the next part.) rad/s The angular acceleration of the assembly is O Problem 16.090.b - Rotation about a fixed point: Equations of motion Determine the magnitude of the couple M. The magnitude of the couple is
