You're replacing the hubcaps on a car. Which of the following are you most likely to use?
claw hammer |
|
wooden mallet |
|
ball-peen hammer |
|
rubber mallet |
A mallet is a hammer with a relatively large head, often made of rubber or wood. Both the size and material of the mallet head help prevent damage when striking more delicate surfaces.
Which of the following is not an advantage of using a ratchet with a larger point-sized socket?
larger point sizes allow greater toque to be applied |
|
all of these are advantages of larger point sizes |
|
larger point sizes are stronger |
|
larger point sizes allow easier alignment |
A ratchet (or socket wrench) is a wrench that applies torque in only one direction with a handle that can be moved back and forth without losing contact with the fastener. A ratchet uses variable attachments called sockets which come in a variety of drive sizes based on the size of the opening that attaches to the ratchet. Sockets with the same drive size will vary in the shape (six-point, twelve-point) and size of the nut opening that attaches to the fastener being tightened or loosened. Smaller point sized sockets are stronger and can apply greater torque while larger point sizes allow easier alignment.
Which of the following saws would you use for creating a curved cut in wood?
back saw |
|
coping saw |
|
hacksaw |
|
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.
Inside and outside micrometers measure inside and outside:
tolerances |
|
lengths |
|
angles |
|
diameters |
Micrometers measure the diameter of cylindrical objects. Outside micrometers measure the external diameter of cylinders and inside micrometers measure the internal diameter of the cylinder's hole.
This tool is a(n) __________.
inside caliper |
|
outside micrometer |
|
inside micrometer |
|
outside caliper |
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.
