What is a micrometer used for?
transferring dimensions between objects |
|
measuring the diameter of cylindrical objects with high precision |
|
measuring length around corners |
|
ensuring that a surface is level |
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.

Which of the following statements about solding is not true?
soldering can only join metals |
|
solder has a comparatively low melting point |
|
flux is used to clean surfaces before soldering |
|
solder is an alloy of lead and tin |
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.
