Which of the following determines whether a socket can be used with a particular ratchet?
the point size |
|
the drive size |
|
the drive circumference |
|
the socket 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.

measure longer distances |
|
measure in tighter spaces |

Which of the following is the primary difference between pliers and pincers?
pliers squeeze, pincers cut or pull |
|
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 |
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.
