PROBLEM 17.42 (Continued)
PROBLEM 17.43
The 4-kg rod AB is attached to a collar of negligible mass at A and to a flywheel
at B. The flywheel has a mass of 16 kg and a radius of gyration of 180 mm.
Knowing that in the position shown the angular velocity of the flywheel is 60 rpm
clockwise, determine the velocity of the flywheel when Point B is directly below C.

PROBLEM 17.44
If in Problem 17.43 the angular velocity of the flywheel is to be the same in the
position shown and when Point B is directly above C, determine the required value
of its angular velocity in the position shown.
PROBLEM 17.43
The 4-kg rod AB is attached to a collar of negligible mass at A
and to a flywheel at B. The flywheel has a mass of 16 kg and a radius of gyration of
180 mm. Knowing that in the position shown the angular velocity of the flywheel is
60 rpm clockwise, determine the velocity of the flywheel when Point B is directly
below C.

PROBLEM 17.45
The uniform rods AB and BC of masses 2.4 kg and 4 kg, respectively,
and the small wheel at C is of negligible mass. If the wheel is moved
slightly to the right and then released, determine the velocity of pin B
after rod AB has rotated through 90 .
PROBLEM 17.46
The uniform rods AB and BC of masses 2.4 kg and 4 kg, respectively,
and the small wheel at C is of negligible mass. Knowing that in the
position shown the velocity of wheel C is 2 m/s to the right,
determine the velocity of pin B after rod AB has rotated through 90.

PROBLEM 17.47
The 80-mm-radius gear shown has a mass of 5 kg and a centroidal radius
of gyration of 60 mm. The 4-kg rod AB is attached to the center of the
gear and to a pin at B that slides freely in a vertical slot. Knowing that the
system is released from rest when
60 ,
determine the velocity of the
center of the gear when
20 .
