You need to loosen a bolt in a hard to reach location. Which of the following wrenches would best suit this task?
open-end |
|
spanner |
|
box-end |
|
adjustable |
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.
Which of the following is not a type of electric-arc welding?
TIG |
|
MIG |
|
stick |
|
oxyacetylene |
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.
The __________ is an initial shallow saw cut made as a guide to prevent the saw from slipping sideways on subsequent more powerful cuts.
groove |
|
channel |
|
guide |
|
kerf |
When you start sawing by creating a kerf it will help prevent the saw from slipping sideways when you begin the power strokes that do most of the cutting.
You need to secure a piece of wood while you're drilling a hole. Which of the following would be the most appropriate tool to use?
vise |
|
pincers |
|
clamp |
|
pliers |
A vise is a clamp that is anchored to a work station and designed to hold material in place while it is being operated upon.
Which of the following statements about welding is not true?
electric-arc welding is safer than oxyacetylene welding |
|
a weld can often be stronger than the base materials alone |
|
no filler metal is required when welding |
|
welding is done at higher temperatures than soldering |
