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.
What is a micrometer used for?
measuring the diameter of cylindrical objects with high precision |
|
ensuring that a surface is level |
|
measuring length around corners |
|
transferring dimensions between objects |
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.
The primary difference between a standard level and a bullseye level is which of the following?
a standard level can measure across two dimensions |
|
a bullseye level can measure across two dimensions |
|
a standard level has only one bubble to center |
|
a bullseye level has only one bubble to center |
Levels utlize a fluid-filled tube containing a bubble that is centered when the surface is horizontal (level) or vertical (plumb) along the direction of the tube. While a standard level can measure along a single dimension, a bullseye level is circular and can indicate the levelness of a two dimensional plane.
Which of the following nuts prevent loosening via nylon in their threads?
lock |
|
slotted |
|
cotter |
|
wing |
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 tools are you more likely to use when woodworking?
rivet |
|
chisel |
|
punch |
|
wrench |
A chisel has a long sharp edge and is used, often in conjunction with a hammer, for cutting. In woodworking, chisels are used to remove large sections of wood to create the initial shape of a design. In metalworking, chisels are used to remove waste metal when a smooth finish is not required.
