4-Bar Mechanism Acceleration Analysis

Input the lengths of the links
fixed link
crank
coupler
output
The mechanis is a crank-rocker since 140+40 < 120+80
angle of the fixed link
start calculating the mechanism displacement
input angle in rad. step each 10 degrees
closure #1
closure #2
closure #1
closure #2
calculate the coordinates of the end points of link #2
calculate the coordinates of the end points of link #2 (closure #1)
calculate the coordinates of the end points of link #2 (closure #2)
Plot the results (end points only). Use polar plots to avoid distortion of the aspect ratio. In polar plot a point is identified using angle and magnitude. Refer all vectors to the same point to get meaningful results.
