You are using a hacksaw to cut a Class 8 bolt. What is the most appropriate TPI for your saw blade?
2 TPI |
|
8 TPI |
|
10 TPI |
|
18 TPI |
A Class 8 bolt is made of very hard metal and larger TPI saw blades are most appropriate for very hard metals.
Which of the following tools are you more likely to use when woodworking?
punch |
|
chisel |
|
rivet |
|
wrench |
A chisel has a long sharp edge and is used, often in conjunction with a hammer, for cutting. In woodworking, chisels are used to remove large sections of wood to create the initial shape of a design. In metalworking, chisels are used to remove waste metal when a smooth finish is not required.
Which of the following saws would you use if you're cutting wood across the grain?
back saw |
|
hacksaw |
|
ripsaw |
|
crosscut 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.
You need to secure two pieces of wood together while the glue between the dries. Which of the following tools is most appropriate?
pliers |
|
rubber band |
|
pincers |
|
clamp |
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.
Screwdrivers are most broadly classified by their:
length |
|
tip |
|
torque |
|
width |
Screwdrivers come in many different handle, shaft, and tip configurations for use in a wide variety of applications. Screwdrivers are classified by their tip which is shaped to fit a corresponding screw head. Common tips are slotted (flat) and Phillips (x-shaped).
