Question:
A 27-kg disk is attached with an eccentricity e = 150μm to the midpoint of a vertical shaft AB which revolves at a constant angular velocity ωf. Knowing that the spring constant k for horizontal movement of the disk is 580kN/m, determine
(a) The angular velocity ωf at which resonance will occur,
(b) The deflection r of the shaft when ωf = 1200 rpm.
Step by Step Answer:

Angular movements are produced when the angle between the bones of joint changes. There are several different types of angular movements, including flexion, extension, hyperextension, abduction, adduction, and circumduction. Flexion, or bending, occurs when the angle between the bones decreases. Moving the forearm upward at the elbow or moving the wrist to move the hand toward the forearm are examples of flexion. The extension is the opposite of flexion in that the angle between the bones of a joint increase.
