You're creating a tube out of a sheet of metal. What type of fastener are you likely to use?
punch |
|
nail |
|
rivet |
|
glue |
A nail is a short pin-shaped shaft of steel that's typically used to fasten pieces of wood together. It has a flat head on one end and a point on the other. A rivet consists of a cylindrical shaft with a head on one end and a tail on the other. When the rivet is installed, the tail is expanded and reshaped to form another head, creating a dumbell shape that will hold two surfaces together semi-permanently.
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?
crosscut saw |
|
hacksaw |
|
coping saw |
|
rip saw |
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 would provide the most accurate measure of the diameter of a solid cylinder?
inside micrometer |
|
outside micrometer |
|
ruler |
|
tape measure |
Micrometers provide accuracy to the thousandths of an inch and come in outside and inside varieties. An outside micrometer is used to measure outside thickness, such as the diameter of a bolt, while an inside micrometer is used to measure the inside dimension of an object, such as the diameter of the hole of a nut or the width of a channel.
