. For a constant clockwise angular velocity of link m of w= 2 rad/s, examine the difference in the path generated by point A at the bottom of the mechanism (i.e. the "foot") as a function of two different element lengths. Specifically, separately change two of the link lengths and study how it impacts the motion of point A. (You may wish to try a few different links until you identify two links that have an interesting impact on the mechanism motion.) Be sure to show the coupler curves of point A as a function of the different element lengths. In particular, focus on the: a. Length of the gait, described as the amount of time A is "in contact with the ground (within X cm of the ground, where you are free to choose a reasonable X). b. Height of the step, defined as vertical distance for which 1/5 of the gait is above that height c. The effective gait velocity of the mechanism as determined by the movement of point A. Explicitly, how fast would it travel over ground given this input angular velocity at link m. d. What is the relationship of angular velocity of link m to the effective calculated above over the range of w = 0 to 10 rad/s? Why is this sensible? Given that Point B and C are fixed, identify at least one 4 bar sub-mechanism which is suitable for analysis in the Linkages program. For a constant clockwise angular velocity of link m of w = 2 rad/s, compare the motion of the 4 bar sub-mechanism with the equivalent motion observed in SolidWorks to justify the output of your SolidWorks model. f h @ d g b i C a BL a=38.0 b=41.5 c=39.3 d=40.1 e=55.8 f=39.4 g=36.7 h=65.7 i=49.0 j=50.0 k=61.9 1= 7.8 m=15.0 .
