(a) Design a planar four-bar linkage using three position synthesis that moves the scoop from theinitial position E, to the final position E3 such that the scoop and all other moving links of thelinkage do not pass through or hit the ground or hit the blue rectangle. You need to select anintermediate scoop position to do the design and ensure that constraints of not hitting the bluerectangle or passing through the ground is satisfied. E₁E3Ground
