This tool is a(n) __________.
vernier caliper |
|
outside caliper |
|
inside caliper |
|
outside micrometer |
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 the primary difference between pliers and pincers?
pincers are designed for large objects, pliers are designed for small objects |
|
pliers squeeze, pincers 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.
The primary difference between a standard level and a bullseye level is which of the following?
a standard level can measure across two dimensions |
|
a standard level has only one bubble to center |
|
a bullseye level can measure across two dimensions |
|
a bullseye level has only one bubble to center |
Levels utlize a fluid-filled tube containing a bubble that is centered when the surface is horizontal (level) or vertical (plumb) along the direction of the tube. While a standard level can measure along a single dimension, a bullseye level is circular and can indicate the levelness of a two dimensional plane.
These tools are called:
planes |
|
chisels |
|
files |
|
rasps |
Wood chisels are used to shape or smooth wood surfaces. They come in a variety of widths and can be used with hand power or tapped with a mallet when deeper cuts need to be made.
The __________ is an initial shallow saw cut made as a guide to prevent the saw from slipping sideways on subsequent more powerful cuts.
channel |
|
kerf |
|
guide |
|
groove |
When you start sawing by creating a kerf it will help prevent the saw from slipping sideways when you begin the power strokes that do most of the cutting.
