Position Analysis
1- The attached figure shows the mechanisms for the problems each of which refers to
the part of the figure having the same letter. Reference all calculated angles to the
global XY axes.
a. The angle between the X and x axes is 25  . Find the angular displacement of
link 4 when 2 rotates clockwise from the position shown (+37  ) to horizontal
(0  ). How does the transmission angle vary and what its minimum between
those two positions?
b. Find and plot the angular position of links 3 and 4 and the transmission angle
as a function of the angle of link 2 as it rotates through one revolution.
c. Find and plot the displacement of piston 4 and the angular displacement of
link 3 as a function of the angular displacement of crank 2.
d. Find and plot the angular displacement of link 6 versus the angle of input
link2 as it is rotated from the position shown (+30
