Which of these saws is used with a miter box?
back saw |
|
crosscut 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.
Which of the following saws would you use for creating a curved cut in wood?
hacksaw |
|
back saw |
|
crosscut saw |
|
coping saw |
Wood saws are categorized by their teeth shape and the number of teeth per inch (TPI). The higher the TPI of a saw the finer the cut it will make. Crosscut saws utilize knife-shaped teeth that cut across the grain of the wood while rip saws cut with the grain using chisel-shaped teeth that rip the wood cells apart as the cut is made. The kerf (slot) made by by a crosscut saw is much smoother than that made by a rip saw but a rip saw cuts much faster. Coping saws are a type of bow saw used to make detailed often curving cuts using replaceable blades with fine small teeth.
A __________ is driven by a motor and used to shape and form edge contours.
chisel |
|
router |
|
file |
|
plane |
A router is a tool that a worker uses to rout (hollow out), shape, or contour an area in relatively hard material like wood or plastic.
Which of the following statements about welding is not true?
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 |
|
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 is not an aspect of the mechanical advantage of pliers?
amplify hand grip force |
|
change the direction of hand grip force |
|
provide precision for manipulating small objects |
|
focus hand grip force |
Pliers are designed to provide a mechanical advantage, allowing the force of the hand's grip to be amplified and focused with precision. Pliers also allow finer control over objects that are too small to be manipulated by the fingers alone. The standard configuration is combination pliers which provide a fixed maximum jaw width. Other styles include adjustable joint pliers that allow selecting jaw width, needle nose pliers for holding small objects in tight spaces and locking pliers that will lock in place to hold or clamp objects together.
