Problem (3)
radius r = 70 mm and is attached to block B as
shown. If the angular velocity of gear D is 20 rpm
A straight rack rests on a gear of
A
counterclockwise when 0 = 20°, determine:
(a) The velocity of block B
(b) The angular velocity of rack AB
Solve the problem one time using the relative velocity equation and another time using the
Instantaneous Center (IC) method. You should get the same answers.
Original Question:
