Which of the following statements about an 8-point saw is not true?
an 8-point saw makes a finer cut than a 12-point saw |
|
an 8-point saw has eight teeth per inch |
|
an 8-point saw makes a rougher cut than a 12-point saw |
|
an 8-point saw makes a rougher cut than a 6-point saw |
Saw blades are described by the number of teeth per inch (TPI). The higher the TPI of a saw the finer the cut it will make.
Which of the following is not a type of nut?
cotter |
|
lock |
|
wing |
|
slotted |
Wrenches are used with threaded fasteners like bolts and nuts. A bolt has external threads while a nut has internal threads and this thread pattern combination allows them to lock together and act as fasteners. Nuts come in a variety of configurations including wing nuts which provide appendages that allow tightening and loosening by hand, slotted nuts that use a cotter pin to lock the nut in place and prevent it from loosening, and lock nuts that also prevent loosening via nylon in their threads. Threads are identified by pitch which is the number of threads per inch.
Which of the following statements about welding is not true?
a weld can often be stronger than the base materials alone |
|
welding is done at higher temperatures than soldering |
|
electric-arc welding is safer than oxyacetylene welding |
|
no filler metal is required when welding |
Welding is a high-temperature process that involves melting the base metals in the objects to be joined to fuse them together. A filler metal is used to provide additional material to make up a joint that, depending on the weld type, can be stronger than the base materials alone. Oxyacetylene welding is a welding process that uses a torch fueled with oxygen and acetylene gases. Electric-arc welding utlizes electric current in a safer welding process (it doesn't involve burning explosive gases) that enables a wide variety of specialized applications like stick, MIG (metal inert gas), and TIG (tungsten inert gas) welding.

Which of the following would be used to make a drilling guide mark in a sheet of metal?
center punch |
|
chisel |

pin punch |
