Which of the following is not an advantage of using a tape measure over using a ruler?
measure in tighter spaces |
|
easier storage |
|
measure with more accuracy |
|
measure longer distances |
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.
You need to secure two pieces of wood together while the glue between the dries. Which of the following tools is most appropriate?
clamp |
|
rubber band |
|
pliers |
|
pincers |
A clamp applies pressure to prevent two objects from moving relative to each other, for example, to keep to pieces of wood together while the glue between the dries. A clamp is commonly made of metal and shaped like the letter C with a perpendicular flat-edged plate providing variable pressure between it and the top of the C as a screw to which it is attached is tightened and released.
This tool is a(n) __________.
outside caliper |
|
inside caliper |
|
vernier caliper |
|
inside 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 saws would you use if you're cutting wood across the grain?
ripsaw |
|
crosscut saw |
|
hacksaw |
|
back saw |
Wood saws are categorized by their teeth shape and the number of teeth per inch (TPI). The higher the TPI of a saw the finer the cut it will make. Crosscut saws utilize knife-shaped teeth that cut across the grain of the wood while rip saws cut with the grain using chisel-shaped teeth that rip the wood cells apart as the cut is made. The kerf (slot) made by by a crosscut saw is much smoother than that made by a rip saw but a rip saw cuts much faster. Coping saws are a type of bow saw used to make detailed often curving cuts using replaceable blades with fine small teeth.
The primary difference between a standard level and a bullseye level is which of the following?
a standard level has only one bubble to center |
|
a standard level can measure across two dimensions |
|
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.
