Problem 1 Apply graphical synthesis to design a crank-rocker fourbar mechanism to give the two positions of the coupler motion as shown in Figure 1. Use the given scale to perform the synthesis. Use points $A$ and $B$ as the moving joints. Set the crank link length to $3\mathrm{cm}$ and the rocker link length to $4\mathrm{cm}$. Determine the following up to graphical accuracy, a) All link lengths, b) Grashof condition, Figure 1: Length of $AB$ is 5
