Question

1. If there is no friction between shaft AB and the collar, what angular velocity θ˙˙ must the mechanism have to keep the collar at r=300 mm from the vertical axis?

Express your answer to three significant figures.

Consider the same mechanism again, with m=2.95 kg, d=225 mm, k=250 N/m, only now, instead of being smooth, the collar and shaft have a maximum coefficient of friction of μs=0.297. What is the minimum angular velocity required to keep the collar at a constant distance r=300 mm from the axis of rotation?

Express your answer to three significant figures.

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 = 2.95 kg. The spring has an unstretched length
of 300 mm and the spring constant is k = 250 N/m.
The distance d = 225 mm, and the collar is required
to stay a fixed distance r = 300 mm from the vertical
axis.(Figure 1)
