Q-2 Figure below shows a shaft that is loaded as given, essentially in bending. Bearings are located at points B and D to allow the shaft to rotate. Pulleys at A, C, and E carry cables that support loads from below while allowing the shaft to rotate. a) Determine the reactions at the bearing supports at B and D. b) Draw shear and bending moment diagrams by completing the figure below. c) Determine the maximum stress due to bending in the shaft considering stress concentrations.

For the process shown in the schematic below, which of the statements is/are incorrect? Feed hopper Feed hopper Plastic pellets Mold cavity Mold Nozzle Spreader Heating chamber Ram Hydraulic pressure Turning screw Barrel Heaters Shaping die Molten plastic Extrudate Select one or more: a. The process can only work with thermoplastics and not with thermosets due to the thermal processing requirements Tubing and pipes Sheet and film Structural parts b. The feedstock has to be molten or liquid monomer, the temperature of which will constantly be held above the melting temperature c. This process is best suited for the large volume production of tubes, bars and beams due to the nature of the extrusion process d. To release the part, the process typically involves the mould sections opening and the ejector pins pushing the object out of the mould De. The mould cavity region is usually temperature controlled so that at the point of injection it is heated and then gradually cooled down until…
