The table gives dimensions for several four bar linkages. Link numbering is defined as follows:

Link 1-Ground link

Link 2- Input link

Link 3-Coupler link

Link 4-Output link

For each linkage, explore the range of motion of the transmission angle, input link, and output

link. All angles are defined in the figure. Specifically, determine the following:

(1)

Determine the maximum and minimum transmission angle. Sketch the linkage in the

positions it occuples when these extremes occur.

ME 3313

(1)

Determine the maximum and minimum of the input angle = . Express your

answers in the positive range 0<<180°. For clarity, sketch a ple chart

approximately to scale that shows the entire possible range of the input angle, including

all circuits.

(1) Repeat part (1) for the output angle = 180-as shown in the figure.
