Which of these saws is used with a miter box?
crosscut saw |
|
back saw |
|
hacksaw |
|
rip saw |
A miter box utlizes a back saw (a fine toothed saw with a rigid strip of steel opposite its blade edge) to make cuts in wood at a specified angle.
The primary difference between a standard level and a bullseye level is which of the following?
a standard level has only one bubble to center |
|
a bullseye level can measure across two dimensions |
|
a bullseye level has only one bubble to center |
|
a standard level can measure across two dimensions |
Levels utlize a fluid-filled tube containing a bubble that is centered when the surface is horizontal (level) or vertical (plumb) along the direction of the tube. While a standard level can measure along a single dimension, a bullseye level is circular and can indicate the levelness of a two dimensional plane.
Which of the following statements about welding is not true?
no filler metal is required when welding |
|
welding is done at higher temperatures than soldering |
|
electric-arc welding is safer than oxyacetylene welding |
|
a weld can often be stronger than the base materials alone |
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?
chisel |
|
screwdriver |
|
center punch |
|
pin punch |
A punch is narrow and is used to drive objects like nails (pin punch) or for making guide marks for drilling (center punch) or patterns in wood or metal.
You're creating a tube out of a sheet of metal. What type of fastener are you likely to use?
punch |
|
nail |
|
rivet |
|
glue |
A nail is a short pin-shaped shaft of steel that's typically used to fasten pieces of wood together. It has a flat head on one end and a point on the other. A rivet consists of a cylindrical shaft with a head on one end and a tail on the other. When the rivet is installed, the tail is expanded and reshaped to form another head, creating a dumbell shape that will hold two surfaces together semi-permanently.
