You've bored a large hole in a piece of wood to insert a doorknob. Which of these tools would you use to smooth the edges of the hole?
file |
|
chisel |
|
rasp |
|
plane |
Files consist of diagonal rows of fine teeth and are used for fine finishing work to smooth, polish, or shape objects. Rasps are files with larger teeth that are used for coarse finishing work. Both files and rasps are designed to be inserted into detachable handles.
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 standard level can measure across two dimensions |
|
a bullseye level can measure across two dimensions |
|
a bullseye level has only one bubble to center |
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.
You're replacing the hubcaps on a car. Which of the following are you most likely to use?
ball-peen hammer |
|
wooden mallet |
|
claw hammer |
|
rubber mallet |
A mallet is a hammer with a relatively large head, often made of rubber or wood. Both the size and material of the mallet head help prevent damage when striking more delicate surfaces.
Which of the following is not a common pliers configuration?
locking |
|
needle nose |
|
wire |
|
adjustable joint |
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.
Which of the following statements about solding is not true?
solder has a comparatively low melting point |
|
soldering can only join metals |
|
solder is an alloy of lead and tin |
|
flux is used to clean surfaces before soldering |
Soldering is a process by which two or more items (typically metal) are joined together by melting a filler metal (solder) into the joint. An electrically powered soldering iron or soldering gun is used to melt the solder which is an alloy of lead and tin that has a melting point below the melting point of the items being joined. A chemical cleaning agent called flux is also used to clean the surfaces before soldering.
