E₁ E3 Ground (a) Design a planar four-bar linkage using three position synthesis that moves the scoop from the initial position E₁ to the final position E3 such that the scoop and all other moving links of the linkage do not pass through or hit the ground or hit the blue rectangle. You need to select an intermediate scoop position to do the design and ensure that constraints of not hitting the blue rectangle or passing through the ground is satisfied. (b) Add two more links and make it a six-bar linkage with a fully rotatable input link. The new dyad that you add should not pass through or hit the ground or hit the blue rectangle. The linkage should be free of defects (branch or circuit defect). A good design should also take into account other practical considerations such as good transmission angle and reasonable link lengths, etc.
