1

The primary difference between a standard level and a bullseye level is which of the following?

54% Answer Correctly

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


Solution

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.

What is a caliper used for?

56% Answer Correctly

making perfectly vertical lines

ensuring that surfaces are level

transferring distances between objects

measuring thickness and irregular shapes


Solution

Calipers are similar to micrometers in shape but instead of measuring distances, calipers are used to transfer distances between objects. An outside caliper is used to transfer outside dimensions while an inside caliper is used to transfer inside distances. A vernier caliper is an extremely precise caliper (down to \({1 \over 1000}\) inch) that allows measuring / transferring either inside or outside dimensions.


3

The primary difference between a claw and a ball-peen hammer is which of the following?

59% Answer Correctly

their size

their non-striking end

their handle shape

their striking end


Solution

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.

This tool is a(n) __________.

62% Answer Correctly

combination wrench

adjustable wrench

open-end wrench

box-end wrench


Solution

Wrenches are used to provide grip and mechanical advantage by applying torque to turn objects (or to keep them from turning). The longer the wrench, the more torque that can be applied. Wrench ends are available in two primary types, open-end and box-end. A box-end wrench encloses the bolt head and is useful when more torque is needed or to maintain contact in difficult to reach locations. An open-end wrench is designed for speedily loosening easier to reach fasteners. Wrenches that feature one open and one box end are called combination wrenches and adjustable wrenches feature an open end with an adjustable width.


5

Which of the following nuts prevent loosening via nylon in their threads?

63% Answer Correctly

slotted

cotter

wing

lock


Solution

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.
