Which of the following determines whether a socket can be used with a particular ratchet?
the socket size |
|
the drive size |
|
the drive circumference |
|
the point size |
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.
You need to secure a piece of wood while you're drilling a hole. Which of the following would be the most appropriate tool to use?
pliers |
|
clamp |
|
pincers |
|
vise |
A vise is a clamp that is anchored to a work station and designed to hold material in place while it is being operated upon.
What is a micrometer used for?
measuring the diameter of cylindrical objects with high precision |
|
ensuring that a surface is level |
|
transferring dimensions between objects |
|
measuring length around corners |
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.
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 |
|
larger point sizes are stronger |
|
larger point sizes allow easier alignment |
|
all of these are advantages of larger point sizes |
