Solve Example 20.5 such that the x, y, z axes move with curvilinear translation, = 0,

Solve Example 20.5 such that the x, y, z axes move with curvilinear translation, Ω = 0, in which case the collar
appears to have both an angular velocity Ω_xyz = ω₁+ ω₂ and radial motion.

Solve Example 20.5

The pendulum shown in Fig. 20-13 consists of two rods; AB is pin supported at A and swings only in the Y-Z plane, whereas a bearing at B allows the attached rod BD to spin about rod AB. At a given instant, the rods have the angular motions shown. Also, a collar C, located 0.2 m from B, has a velocity of 3 m/s and an acceleration of 2 m/s² along the rod. Determine the velocity and acceleration of the collar at this instant.
