Which of the following is not a common pliers configuration?
wire |
|
needle nose |
|
adjustable joint |
|
locking |
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 tools are you more likely to use when woodworking?
wrench |
|
punch |
|
chisel |
|
rivet |
A chisel has a long sharp edge and is used, often in conjunction with a hammer, for cutting. In woodworking, chisels are used to remove large sections of wood to create the initial shape of a design. In metalworking, chisels are used to remove waste metal when a smooth finish is not required.
Which of the following is not an advantage of using a ratchet with a larger point-sized socket?
larger point sizes are stronger |
|
all of these are advantages of larger point sizes |
|
larger point sizes allow easier alignment |
|
larger point sizes allow greater toque to be applied |
A ratchet (or socket wrench) is a wrench that applies torque in only one direction with a handle that can be moved back and forth without losing contact with the fastener. A ratchet uses variable attachments called sockets which come in a variety of drive sizes based on the size of the opening that attaches to the ratchet. Sockets with the same drive size will vary in the shape (six-point, twelve-point) and size of the nut opening that attaches to the fastener being tightened or loosened. Smaller point sized sockets are stronger and can apply greater torque while larger point sizes allow easier alignment.
Which of the following statements about solding is not true?
flux is used to clean surfaces before soldering |
|
soldering can only join metals |
|
solder is an alloy of lead and tin |
|
solder has a comparatively low melting point |
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.
Which of the following statements about an 8-point saw is not true?
an 8-point saw has eight teeth per inch |
|
an 8-point saw makes a rougher cut than a 6-point saw |
|
an 8-point saw makes a finer cut than a 12-point saw |
|
an 8-point saw makes a rougher cut than a 12-point saw |
Saw blades are described by the number of teeth per inch (TPI). The higher the TPI of a saw the finer the cut it will make.
