Project 1 Part 3

You will be given the angle, a, but you need to adjust the height (b1 and b2) in order for the total force upward equals to Fz.

Since (b1-b2) / 2mm = sin(a) is always true. We want to adjust the value b1 and b2 but make sure that the difference between the two satisfies the equation above.

So you can pick b2, then b1 = b2 + (2mm)*sin(a). Then calculate locations of each keypoints using the new b1 and b2.

KP 1 = (0,0,0)
KP 2 = (2mm / cos(a), 0, 0 )
KP 3 = (2mm / cos(a) + b2 * sin(a) , -b2 / cos(a) , 0)
KP 4 = (b1 * sin(a) , -b1 / cos(a) , 0)
KP 5 =(0,0,-W)
KP 6 = (2mm / cos(a), 0, -W)
KP 7 = (2mm / cos(a) + b2 * sin(a) , -b2 / cos(a) , -W)
KP 8 = (b1*sin(a) , -b1 / cos(a) , -W)

Repeat the same steps as in project 1 part 1 except that change coordinates for keypoint 1through 8 to be as follows.
