Which of the following statements about solding is not true?

56% Answer Correctly

flux is used to clean surfaces before soldering

solder has a comparatively low melting point

solder is an alloy of lead and tin

soldering can only join metals


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.

Which of the following types of saws would you use if you needed to cut the wood quickly and weren't concerned with leaving rough edges?

55% Answer Correctly

hacksaw

rip saw

coping saw

crosscut saw


Solution

Wood saws are categorized primarily by their teeth. Crosscut saws utilize knife-shaped teeth that cut across the grain of the wood while rip saws cut with the grain using chisel-shaped teeth that rip the wood cells apart as the cut is made. The kerf (slot) made by by a crosscut saw is much smoother than that made by a rip saw but a rip saw cuts much faster. Coping saws are a type of bow saw used to make detailed often curving cuts using replaceable blades with fine small teeth.


5

Which of the following is not an aspect of the mechanical advantage of pliers?

61% Answer Correctly

change the direction of hand grip force

focus hand grip force

amplify hand grip force

provide precision for manipulating small objects


Solution

Pliers are designed to provide a mechanical advantage, allowing the force of the hand's grip to be amplified and focused with precision. Pliers also allow finer control over objects that are too small to be manipulated by the fingers alone. The standard configuration is combination pliers which provide a fixed maximum jaw width. Other styles include adjustable joint pliers that allow selecting jaw width, needle nose pliers for holding small objects in tight spaces and locking pliers that will lock in place to hold or clamp objects together.
