6-53 A
conical
pendulum
(Figure 5-25) consists of a mass (the bob) on the end of a string. As
the
bob
travels in a horizontal circle at constant speed, the string traces out
a cone. For the pendulum shown, mass m = 1.95 kg,
length
l = 1.03 m, and angle q = 36.9°.(a) Draw a free
body diagram for the bob at the instant shown.
(b) What force
constitutes the centripetal force?
(c) Determine the
speed of the bob.
What is the FBD of the pendulum bob?
