Concept explainers
Go to the local hardware or building supply store and examine a specific class of fastener (nail, screw, bolt, rivet, etc.). Is it available in different grades or classes based on strength or intended use? What are they, and how do they differ? How might the materials and methods of manufacture be different for these identified groups? Summarize your findings. What surface treatments, if any, have been applied to the items? How was it applied and for what purpose?

- 8. Design Problem: A material is needed to support a hanging sculpture with an overall tensile load of 800 N. It is important that the material not undergo any permanent deformation under this load and must have minimum volume/diameter. Using a circular rod, design structural components using your data for each of the three materials. Which material would you choose for the application and why? If the requirement was minimum weight, rather than minimum volume, which material would you use? Show sample calculations.arrow_forward6arrow_forwardExplain in your own words how the stress test (performance test) is applied to the patient turning apparatus shown in the figure, and guess how the expected result will be. The main part of the product consists of a polyurethane sponge. Stain-proof upholstery fabric will be used as the outer surface material. In addition, there are heating pads working with the logic of electric blankets in this apparatus, please answer by taking these into account when answering.arrow_forward
- What are some examples of an application of the Lever Rule and explain?arrow_forwardA pipe can be manufactured as (a) seamless (cold rolled and extruded) or (b) hot rolled and welded. (i) Describe the process for manufacturing each type of pipe: (a) Seamless (cold rolled and extruded) pipe; (b) Hot rolled and welded pipe. (ii) Why might a cold rolled seamless pipe be better suited to drilling operations than a hot rolled and welded pipe? A particle reinforced composite (containing flakes) has particles evenly distributed throughout the matrix where the rule of mixtures applies. (i) State THREE effects that a larger volume of carbon particles within the matrix produces. A drill bit is a cutting tool on the end of a rotary subsea drill. A Thermally Stable Polycrystalline (TSP) drill bit can be used to drill a subsea well. TSP bits are man-made polycrystalline structures consisting of a multitude of synthetic diamond crystals sintered together at high pressure and temperature, used to aid cutting into hard rock formations. (i) Describe THREE reasons why this type…arrow_forward(4) The average flow stress is the flow stress multiplied by which of the following factors: (a) n, (b) (1-n), (c) 1/n, or (d) 1/(1+n), where n is the strain hardening exponent? (5) The strength of a brazed joint is typically (a) equal to, (b) stronger than, or (c) weaker than soldered joint? (6) Thread cutting operation is normally performed on which one of the following machine tools: (a) drill press, (b) lathe, (c) milling machine, (d) planer, or (e shaper? (7) Of the following cutting conditions, which one has the greatest effect on cutting temperature: (a) cutting speed, (b) depth of cut, or (c) feed? (8) The maximum possible draft in a rolling operation depends on which of the following parameters (two correct answers): (a) coefficient of friction, (b) roll diameter, (c) roll velocity, (d) stock thickness, (e) strainarrow_forward
