Which of the following is the primary difference between pliers and pincers?

61% Answer Correctly

pincers are designed for large objects, pliers are designed for small objects

pincers squeeze, pliers cut or pull

pliers are designed for large objects, pincers are designed for small objects

pliers squeeze, pincers cut or pull


Solution

Pincers provide a mechanical advantage that's used to cut, pinch or pull an object. The force applied to pincers is concentrated to a point or to an edge of the tool which allows pincers to be brought very close to a surface. Pincers are typically used for removing objects from a material to which they've previously been applied, for example, to pull nails from wood.

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

63% Answer Correctly

slotted

cotter

lock

wing


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.

This tool is a(n) __________.

86% 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 statements about solding is not true?

56% Answer Correctly

solder has a comparatively low melting point

flux is used to clean surfaces before soldering

soldering can only join metals

solder is an alloy of lead and tin


Solution

Soldering is a process by which two or more items (typically metal) are joined together by melting a filler metal (solder) into the joint. An electrically powered soldering iron or soldering gun is used to melt the solder which is an alloy of lead and tin that has a melting point below the melting point of the items being joined. A chemical cleaning agent called flux is also used to clean the surfaces before soldering.
