Which of the following would be used to make a drilling guide mark in a sheet of metal?
screwdriver |
|
pin punch |
|
chisel |
|
center punch |
A punch is narrow and is used to drive objects like nails (pin punch) or for making guide marks for drilling (center punch) or patterns in wood or metal.
Which of the following would provide the most accurate measure of the diameter of a solid cylinder?
outside micrometer |
|
ruler |
|
tape measure |
|
inside micrometer |
Micrometers provide accuracy to the thousandths of an inch and come in outside and inside varieties. An outside micrometer is used to measure outside thickness, such as the diameter of a bolt, while an inside micrometer is used to measure the inside dimension of an object, such as the diameter of the hole of a nut or the width of a channel.

Which of the following is not an advantage of using a ratchet with a larger point-sized socket?
larger point sizes allow greater toque to be applied |
|
larger point sizes are stronger |
|
all of these are advantages of larger point sizes |
|
larger point sizes allow easier alignment |
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.
This tool is a(n) __________.
inside caliper |
|
outside micrometer |
|
vernier caliper |
|
outside 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.
