Question

If there is no friction between shaft AB and the collar, what angular velocity Ö must the mechanism have to keep the collar at r= 660 mm from the vertical axis?

Consider the same mechanism again, with m = 3.3 kg, d = 275 mm, k = 180 N/m, only now, instead of being smooth, the collar and shaft have a maximum
coefficient of friction of 0.74. What is the minimum angular velocity required to keep the collar at a constant distance r= 660 mm from the axis of rotation?

Learning Goal:
To set up and analyze equations of motion in a cylindrical coordinate
system.
The mechanism shown in the figure below rotates about the vertical
axis. The collar has mass m = 3.3 kg. The spring has an
unstretched length of 420 mm and the spring constant is
k = 180 N/m. The distance d = 275 mm, and the collar is
required to stay a fixed distance r = 660 mm from the vertical axis.
