Unformatted text preview: θ with the line OA . The instantaneous center of rotation of the connecting rod at a given time is the point C where the horizontal line through A intersects the extended line through O and B . From Figure 1.3.2 we see that ∠ OAC = 90 ◦ , and we let a = AC , b = AB , and c = BC . In the exercises you will show that for ◦ < θ < 90 ◦ , c = r b 2 − r 2 sin 2 θ cos θ and a = r sin θ + r b 2 − r 2 sin 2 θ tan θ ....
