When compared to drilling, boring makes __________ holes.
rougher |
|
larger |
|
smoother |
|
smaller |
Drilling is the process of making small holes in wood or metal while boring is the process of making larger holes.
What is a caliper used for?
transferring distances between objects |
|
ensuring that surfaces are level |
|
making perfectly vertical lines |
|
measuring thickness and irregular shapes |
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.
Which of the following determines whether a socket can be used with a particular ratchet?
the drive size |
|
the point size |
|
the socket size |
|
the drive circumference |
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 is the primary difference between pliers and pincers?
pincers are designed for large objects, pliers are designed for small objects |
|
pincers squeeze, pliers cut or pull |
|
pliers are designed for large objects, pincers are designed for small objects |
|
pliers squeeze, pincers cut or pull |
Pincers provide a mechanical advantage that's used to cut, pinch or pull an object. The force applied to pincers is concentrated to a point or to an edge of the tool which allows pincers to be brought very close to a surface. Pincers are typically used for removing objects from a material to which they've previously been applied, for example, to pull nails from wood.
Which of the following is not an advantage of using a tape measure over using a ruler?
easier storage |
|
measure with more accuracy |
|
measure longer distances |
|
measure in tighter spaces |
Rulers are used to both measure distance and to draw straight lines. Tape measures are flexible rulers useful for measuring longer distances and in tighter spaces. Rulers and tape measures provide similarly accurate measurements.
