A mechanical aim rotates in the vertical plan about point O. The slider P (m = 2 kg) is drawn toward O with a constant speed (?̇) of 0.5 m/s through the rough slot (friction coefficient µ = 0.1) by pulling on the free end E of the cord. At the instant when r = 0.25 m, the arm is rotating with a constant speed (?̇) of 10 rad/s in the clockwise direction.

When the slider is oriented at an angle of θ = 30° from the horizontal:

a) Plot the free body diagram for P, using r-? coordiantes; show positive r and ? directions (4 points)

b) Determine the normal force between the slider and the slot, in N (7 points)

c) Determine the tension in the cord, in N (7 points)

d) Which side (A or B) is in contact with the slider? Why? (2 points)

a uniform spherical shell of mass M and radius R rotates about a vertical axis on...

a uniform spherical shell of mass M and radius R rotates about a vertical axis on frictionless bearing. A massless cord passes around the equator of the shell, over a pulley of rotational inertia I and radius r, and is attached to a small object of mass m. There is no friction on the pulley's axle; the cord does not slip on the pulley. What is the speed of the object after it has fallen a distance h from rest?...
