Which of the following types of saws would you use if you needed to cut the wood quickly and weren't concerned with leaving rough edges?
rip saw |
|
coping saw |
|
crosscut saw |
|
hacksaw |
Wood saws are categorized primarily by their teeth. 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.
Which of the following statements about an 8-point saw is not true?

|
an 8-point saw makes a finer cut than a 12-point saw |
|
an 8-point saw has eight teeth per inch |
|
an 8-point saw makes a rougher cut than a 6-point saw |
Saw blades are described by the number of teeth per inch (TPI). The higher the TPI of a saw the finer the cut it will make.
This tool is a(n) __________.
open-end wrench |
|
combination wrench |
|
box-end wrench |
|
adjustable wrench |
Wrenches are used to provide grip and mechanical advantage by applying torque to turn objects (or to keep them from turning). The longer the wrench, the more torque that can be applied. Wrench ends are available in two primary types, open-end and box-end. A box-end wrench encloses the bolt head and is useful when more torque is needed or to maintain contact in difficult to reach locations. An open-end wrench is designed for speedily loosening easier to reach fasteners. Wrenches that feature one open and one box end are called combination wrenches and adjustable wrenches feature an open end with an adjustable width.
