d = 1.49 kg/m-s. For steel, take p≈ 7800 kg/m³.

It is a good practice to include an isometric view without hidden lines as one of the views in your drawing. True? A. Good practice, same scale as principal views B. Good practice; scales can be modified C. Good practice, bust most use hidden lines D. No, isometric view should not be needed or included     ANSI standards dictate the style, dimensions and arrangement of engineering working drawing layouts: A. Yes, they must be followed to ensure…… B. No companies are expected to adhere to the standards but have the latitude to the customize according to individual needs.

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…

Match patterns representing different materials are allowable and specified by drawing standards. True? A. Yes B. No, they may be represented at the engineering discretion   Instead of using multiple sections for different features, I can cluster them under a single section using A. An offset section B. A half section C. A Multiview section D. None of the above
