A slider crank mechanism is selected for this purpose. The mechanism depicted in Figure 1 has a gearbox-coupled electric motor that drives a chain sprocket mechanism. The speed of the motor shaft is reduced to \( 1: 7^{\text {th }} \) at the gearbox exit. The main shaft of the conveyor feed mechanism carries the driven sprocket and crank link (2) with two supporting bearings. The connecting rod (3) connects the crank (2) and slider (4) by pins at A and B. The slider (4) is welded to the pusher rod. Figure 1 Conveyor Feed Mechanism As an engineering approach, the weights of the links and the friction between mating surfaces, except for the one between the cargo and conveyors are to be neglected. The calculations and the design of various components of such a mechanism are asked in this project. The entire design should be made for the system being in the horizontal crank position \( \theta=0^{\circ} \), as shown in Figure 1. A. Force Analysis Draw the free-body diagrams of the following parts and determine the forces acting on the following parts. 1. Link \( 2,3,4 \) 2. Pin B 3. Shaft \( \mathbf{S} \) 4. Sprockets
