Industrial Mechanics 4th Edition Chapter 3: Fastening Methods Complete Questions And Answers

adhesive - Answer-A substance that is used to bond materials together at the surface. tapping - Answer-The forming of internal threads in a material. pin - Answer-A cylindrical fastener that is placed into a hole to secure the relative positions of two or more parts. washer - Answer-A small metallic disc with a hole in its center used under the head of a bolt or screw, and/or under a nut, to spread the load (tightening force) over a larger area. adhesive tape - Answer-A strip of material coated on one or both sides with an adhesive and used for the purpose of fastening. shielded metal arc welding (SMAW) - Answer-An arc welding process in which the arc is shielded from impurities by the gases emitted from the decomposition of a consumable electrode covering. nail - Answer-A small metal, rod-shaped spike with a broadened circular head that is driven typically into wood with a hammer. self-tapping screw - Answer-A threaded fastener with a tapered point and screw threads that bite into a compressible or deformable material is it is driven. machine screw - Answer-A fully threaded fastener with an internal drive recess that is intended to be engaged into an internally threaded material. cyanoacrylate adhesive - Answer-An acrylic polymer resin adhesive that bonds very ring - Answer-A joining process that joins parts by heating a filler metal to temperatures up to 840° F but less than the melting point of the base metal. bolt - Answer-A large, partially threaded fastener with no internal drives recess that is intended to be used with a nut. nut - Answer-A small block of metal with an internally threaded hole that is threaded onto the end of a matching bolt or machine screw to assemble a stack of parts. contact adhesive - Answer-A flexible synthetic adhesive that is applied separately to two surfaces, which are then brought into contact. oxyfuel welding (OFW) - Answer-A welding process that produces heat from the combustion of a mixture of oxygen and a fuel gas. tensile strength - Answer-The maximum load in tension (pulling apart) that a material can withstand before breaking or fracturing. polyurethane adhesive - Answer-A durable synthetic resin polymer adhesive available in multiple variations, each optimized for different applications. gas tungsten arc welding (GTAW) - Answer-An arc welding process in which a shielding gas protects the arc between a tungsten electrode and the weld area. welding - Answer-A joining process that fuses materials by heating them to melting temperature. polymer - Answer-A molecule made up of a chain of repeating units that are chemically bonded together. key - Answer-A small removable piece of steel of standard shape and dimensions that is placed in a keyseat between a shaft and hub to provide a means for transmitting welding - Answer-A welding process that uses the electrical resistance of an arc bridging a gap to generate the heat necessary for melting a workpiece. epoxy adhesive - Answer-A synthetic polymer resin adhesive that is chemically cured from two mixed liquids. screw thread - Answer-A ridge in the form of a spiral on the internal or external surface of a cylinder or cone. threaded fastener - Answer-A device that joins parts together with a screw thread. gas metal arc welding (GMAW) - Answer-An arc welding process that uses a continuous wire electrode. polymer adhesive - Answer-A synthetic bonding substance that undergoes a chemical or physical reaction. keyseat - Answer-A groove along the axis of a shaft or hub. rivet - Answer-A permanent mechanical fastener with a cylindrical shaft, a preformed head on one end, and a head on the other that is formed in place. brazing - Answer-A joining process that joins parts by heating a filler metal to temperatures greater than 840°F but less than the melting point of the base metal. fastening - Answer-A process that affixes one part to another. screw drive - Answer-A standardized internal shape recessed in a screw head that allows the screw to be rotated with a matching tool. oxyacetylene welding (OAW) - Answer-An oxyfuel welding process that uses oxygen mixed with acetylene.
