The particle of mass m = 1.9 kg is attached to the light rigid rod of length L = 0.76 m, and the assembly rotates about a horizontal axis through O with a constant angular velocity θ˙ = ω = 2.3 rad/s. Determine the force T in the rod when θ = 20°. The force T is positive if in tension, negative if in compression. Please refer to the figure below.

Definition Definition Rate of change of angular displacement. Angular velocity indicates how fast an object is rotating. It is a vector quantity and has both magnitude and direction. The magnitude of angular velocity is represented by the length of the vector and the direction of angular velocity is represented by the right-hand thumb rule. It is generally represented by ω.
