The 0.5-kg pin P is constrained to move in the smooth curved slot, which is defined by the lemniscate r= (0.6 cos 8) m. Its motion is controlled by the rotation of the slotted arm OA, which has a constant clockwise angular velocity of = -3 rad/s. (Figure 1) Figure O r= (0.6 cos 20) m 1 of 1 A Part A Determine the force arm OA exerts on the pin P when 8 = 0°. Motion is in the vertical plane.

Forced undamped vibrations

In mechanical engineering, vibration is expressed as the term that occurs due to an object's backward and forward movement about a point of equilibrium. Generally, there are three types of vibrations which are,
