Computer Aided Engineering Design

INTRODUCTION 21

into the rectangular groove of the film, moves along a straight line by 35 mm and then lifts up to disengage

from the film at the end of its motion. Design the mechanism by selecting suitable sizes of the linkages.

Links 2 and 4 are parallel.

4. For the mechanism shown in Fig. P1.4, the input angle θ 2 = 60°, and the constant angular velocity ω 2 = 5
   radians/sec (CCW). If body 4 is in rolling contact with the ground, determine the velocity and acceleration
