Unformatted text preview: ME 352 - Machine Design I Name
Spring 2012 Lab. Div. Number Homework No. 3
Due: Friday, February 3, 2012 1) Refer to problem 3.29 on p. 162 of the ME 352 text: Theory of Machines and Mechanisms, and
determine the following:
(a) Vector loop equation including the unknowns.
(b) Position solution using the closed form solution.
(c) Kinematic coefficients and the angular velocity of the follower.
(d) Rolling contact equation and the kinematic coefﬁcient of the roller.
(e) Angular velocity of the roller. 2) For the mechanism shown below, the position solution for r; = 3 inches is given below. If the
velocity of link 2 is 10 ﬁ/sec to the left, use kinematic coefﬁcients to determine f4 and @4. r4 = 2.45 inches where rl =1 inch 8] = 90 degrees @3 = 147.67 degrees r3 --= 2 inches ...
