Which of the following determines whether a socket can be used with a particular ratchet?
the socket size |
|
the drive size |
|
the drive circumference |
|
the point size |
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) __________.
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.
Which of the following is not an advantage of using a ratchet with a larger point-sized socket?
all of these are advantages of larger point sizes |
|
larger point sizes allow easier alignment |
|
larger point sizes are stronger |
|
larger point sizes allow greater toque to be applied |
