The primary difference between a claw and a ball-peen hammer is which of the following?
their handle shape |
|
their striking end |
|
their non-striking end |
|
their size |
The most common striking tool is the hammer and the most common variety of hammer is the claw hammer. The claw hammer has two ends, one to drive nails and one to remove nails. Ball-peen hammers replace the claw with a rounded end that's used to round off the edges of metal pins and make gaskets.
A __________ is driven by a motor and used to shape and form edge contours.
chisel |
|
router |
|
plane |
|
file |
A router is a tool that a worker uses to rout (hollow out), shape, or contour an area in relatively hard material like wood or plastic.
Which of the following is not a type of nut?
slotted |
|
cotter |
|
wing |
|
lock |
Wrenches are used with threaded fasteners like bolts and nuts. A bolt has external threads while a nut has internal threads and this thread pattern combination allows them to lock together and act as fasteners. Nuts come in a variety of configurations including wing nuts which provide appendages that allow tightening and loosening by hand, slotted nuts that use a cotter pin to lock the nut in place and prevent it from loosening, and lock nuts that also prevent loosening via nylon in their threads. Threads are identified by pitch which is the number of threads per inch.
Which of the following is not an advantage of using a ratchet with a larger point-sized socket?
larger point sizes are stronger |
|
larger point sizes allow greater toque to be applied |
|
all of these are advantages of larger point sizes |
|
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 would provide the most accurate measure of the diameter of a solid cylinder?
outside micrometer |
|
ruler |
|
tape measure |
|
inside micrometer |
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.
