A four-bar linkage system is shown below. The first link, a, is an input link (crank) of length 1m. The second link, b, is a coupler link of length 2m. The third link, c, is an output link of length 3m. The fourth link, d, is the fixed link (ground) of length 4m. d - cos 04 a The angular position of the output link (84) of a four-bar linkage corresponding to the angular position of the input link (0) can be computed using Freudenstein's equation: d d - cos 0 + C 0 ab + c + d 2ac = cos(0 - 04) = Using the modified secant method to determine the value of 04 when 02 40. With an initial guess of x; = 100, perturbation 8 = 0.01 and precision of 0.0001.
