For this project, I decided to build a pump-jack/oil drill. This mechanism is similar to the one we worked on for homework 3 and 5, which is shown in Figure 1, but with different dimensions.
Figure 1-A pump-jack mechanism found in Chapter 6 and 7
This resulted in the following mechanism:
Figure 2-Completed pump-jack mechanism
The dimensions that I selected are as follows:
O4B = 5 inches
AB = 7.5 inches
O4 ground = 8 inches
O2 ground = 3 inches
O2A = 2 inches
Px = 10 inches
Py = 3.5 inches
α = 126.5 degrees
