Which of the following saws would you use if you're cutting wood along the grain?
hacksaw |
|
back saw |
|
ripsaw |
|
crosscut saw |
The ripsaw delivers maximum efficiency at cutting with or along the grain (ripping).
Which of the following is not a type of electric-arc welding?
MIG |
|
oxyacetylene |
|
TIG |
|
stick |
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.
When compared to drilling, boring makes __________ holes.
larger |
|
smoother |
|
rougher |
|
smaller |
Drilling is the process of making small holes in wood or metal while boring is the process of making larger holes.
Which of the following statements about welding is not true?
no filler metal is required when welding |
|
a weld can often be stronger than the base materials alone |
|
electric-arc welding is safer than oxyacetylene welding |
|
welding is done at higher temperatures than soldering |

This tool is a(n) __________.
box-end wrench |
|
open-end wrench |
|
adjustable wrench |
|
combination wrench |
Wrenches are used to provide grip and mechanical advantage by applying torque to turn objects (or to keep them from turning). The longer the wrench, the more torque that can be applied. Wrench ends are available in two primary types, open-end and box-end. A box-end wrench encloses the bolt head and is useful when more torque is needed or to maintain contact in difficult to reach locations. An open-end wrench is designed for speedily loosening easier to reach fasteners. Wrenches that feature one open and one box end are called combination wrenches and adjustable wrenches feature an open end with an adjustable width.
