Your task is to modify the Mathematica Notebook of Assignment 5
in order to simulate the

inverted slider-crank linkage shown in Figure 6-19 on page 271 of the
text by Norton.

Link 2 is the input link. Simulate and animate the device for one complete rotation of the input link.

Data:

Angle O4-O2-A = 120 deg.

omega2 = 1.5 rad/sec, const.

length O2-O4 = 4 units

length O2-A = 2 units

length O4-C = 1 unit

where point C is the intersection between lines A-B and I(1,3)-I(3,4).
