Project Results

The results of the kinematic analysis are provided below. The first three graphs are for the penguin body.

These results make sense considering I modeled the cam as a third order polynomial. In the position graph, the body moves up as I rotate the crank until 225 degrees when it hits the drop in the came and then remains constant over the constant radius. Then the velocity is a quadratic shape, because it is found by taking the derivative of the body. Also, the acceleration graph is linear because it is the second derivative of the position function. The following three graphs are the wing position, velocity and acceleration.

One of the notable things about these graphs is that they are not typical first, second and third order polynomial graphs like those for the body. This is because the tangent components to the wing from the body velocity and acceleration change as a function of cos(theta). The wing tip goes from approximately -30 degrees to about 70 degrees. The velocity of the wing tip hits it's maximum when the wing angle is 0 degrees, this makes sense as the entire velocity of the body is tangent to the wing.
