Problem 4
For the 6 bar Watt's mechanism shown below, the link lengths are as follows: O2A = 1, AB = 1.2,
0204 = 2, 04B = 2, 0406 = 1.9, 06D = 2.4, CD = 1. Also O4C = 04B = BC. The input
angle is 02. For 02 = 45 degrees, find the positions of the moving pivots A, B, C, and D in the
global coordinate system YO2X. 0406 makes an angle of -30 degrees with the horizontal axis.
