ME 244 Assignment 7 Spring 2010 Department of Mechanical Engineering, Yeditepe University Due date: 09 April 2010, Friday - 5 PM Policy: The assignments should be done by each student individually, not as group work. The due date and time is Friday 5 PM, one week after the assignment is given. No late submissions are accepted. The assignments should be submitted to the Teaching Assistant of the course, Batuhan Baturalp (Room A702). 1. Determine the velocity of rod R for any angle θ of the cam C if the cam rotates with a constant angular velocity ω . The pin connection at O does not cause an interference with the motion of A on C. 2. The planetary gear system is used in an automatic transmission for an automobile.

Unformatted text preview: By locking or releasing certain gears, it has the advantage of operating the car at diﬀerent speeds. Consider the case where the ring gear R is rotating with angular velocity w R = 3 rad/s, and the sun gear S is held ﬁxed, w S = 0. Determine the angular velocity of each of the planet gears P and shaft A. 3. Due to slipping, points A and B on the rim of the disk have the velocities v A = 1 . 5 m/s and v B = 3 m/s. Determine the velocity of the center point C at this instant. The radius of the disk is 0 . 25 m. 1 Figure 1: Question 1 Figure 2: Question 2 Figure 3: Question 3 2...
