Which of the following is not an advantage of using a ratchet with a larger point-sized socket?
larger point sizes allow easier alignment |
|
larger point sizes allow greater toque to be applied |
|
all of these are advantages of larger point sizes |
|
larger point sizes are stronger |
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 types of saws would you use if you needed to cut the wood quickly and weren't concerned with leaving rough edges?
coping saw |
|
hacksaw |
|
crosscut saw |
|
rip saw |
Wood saws are categorized primarily by their teeth. 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.
This tool is a(n) __________.
outside micrometer |
|
inside caliper |
|
outside caliper |
|
vernier caliper |
Calipers are similar to micrometers in shape but instead of measuring distances, calipers are used to transfer distances between objects. An outside caliper is used to transfer outside dimensions while an inside caliper is used to transfer inside distances. A vernier caliper is an extremely precise caliper (down to \({1 \over 1000}\) inch) that allows measuring / transferring either inside or outside dimensions.
The primary difference between a claw and a ball-peen hammer is which of the following?
their size |

The most common striking tool is the hammer and the most common variety of hammer is the claw hammer. The claw hammer has two ends, one to drive nails and one to remove nails. Ball-peen hammers replace the claw with a rounded end that's used to round off the edges of metal pins and make gaskets.
Which of the following saws is not good for cutting wood?
hacksaw |
|
ripsaw |
|
crosscut saw |
