Measuring Tools

A reamer is a cutting tool used for finishing work on holes that have been made with a drill or borer. The reamer can finish of the hole to the exact diameter required and also smooth the edge.

A digital micrometer is used to measure small distances in the engineering and manufacturing field. It can measure wires, shafts, spheres, bolts, blocks, and holes.

If you are measuring it's length, a ruler is adequate

A little under 2 feet.

you would probably use millimetres because a honey bee is pretty tiny.

No, a lever is any abject used to provide leverage with a fulcrum & looks like a teeter totter to pry on something.

A ruler made of stainless steel.

If its the distance in a car/bus/walking/ect. then I would go in google maps, then click the get directions. Put in both locations and it will tell you the distance.

A ruler and a calculator. Or a math text book.

Anyone who is wondering the advantage of using a steel rule over a wooden one they would quickly find that the steel rule is much more durable and easy to read. The wooden rule is quite prone to break if accidentally used wrong.

You do not need "white rods", you need a tape measure or a ruler to measure the lenght of your thumb.

The best leatherman tool for backpacking is a multi tool. If something happens or is needed you will most likely have a tool for that.

The level holds a tube of oil with 2 marks set 5millemetres apart at its centre. a bubble of air will travel along the tube in the opposite direction to the angle the level is held at. When the bubble sits between the 2 lines it indicated that level is either horizontal or if the tube is set so it can indicate a vertical then it shows that the level is vertical . Used by builders in the main it helps them ensure that items are true vertical ( a wall for instance) or true horizontal (a kitchen work top for instance)

A scale.

A hygrometer measures humidity.

1. To avoid lifting of the bridge of the depth micrometer, make sure that the spindle is correctly positioned before taking a reading. The spindle should be parallel to the base of the depth micrometer and should be positioned directly over the object being measured.
2. Make sure that the object being measured is firmly supported and that the work surface is free of debris that may interfere with the depth micrometer’s operation.
3. Before taking a reading, check that the anvil and spindle are perfectly aligned with each other.
4. Avoid pressing down on the depth micrometer too hard as this can cause the bridge to lift.
5. Always use the correct size micrometer for the job and the correct size anvil for the object being measured.
6. If the bridge does start to lift, stop and correct the problem before taking any further readings.
7. Before taking a reading, always make sure that the depth micrometer is properly zeroed.
8. When using a depth micrometer, always keep your hand away from the spindle and anvil.
9. Make sure that the depth micrometer is properly maintained and stored in a dry, clean environment.
10. Lastly, always use the depth micrometer with care and caution to avoid any damage or inaccuracy.

A flexible steel rule, spring assisted, that coils to its own case after use

A vernier caliper

Their Vernier scale consists of two readings; the Vernier scale and the main scale. One can read that by the first line is the main scale and the next line is the Vernier reading.

The term rule in this context is synonymous with ruler, a marked strip that can be used to measure length. A flexible steel rule is make of thin, flexible steel.

The vertical angles are all measured from an assumed horizontal plane....e.g. level ground. So the instrument must be carefully "leveled" when you set it up (usually on a tripod). The course adjustment for the instrument starts with the tripod legs, then the leveling screws of the base, and the leveling of the sight tube. Rotating the instrument to various horizontal azimuths helps to confirm the instrument is level no matter which direction it faces.

Horizontal angles are often referenced to North (which can be either true north or magnetic north) but on building construction sites, its more important to align to a structural element of the building, usually a side of the foundation. So many times a corner point serves as the start and all horizontal angles are measured relative to a side of the structure starting from the corner point to another corner point.

The precision of the theodolite lies in the direct reading micrometer scale in the telescope (sighting tube). The transit (the poor brother of the theodolite) often uses vernier scales for measurement. When you sight on the target with the telescope, the horizontal angle is read off the circle (scale at the rotating base of the telescope), and the vertical angle is read directly from the micrometer scale seen in the telescope.

Its a good practice to take a reading and record both angles. Then rotate the telescope completely in one direction (say clockwise) and take a second reading and record both angles. Then rotate the telescope completely in the opposite direction and take a third set of readings and record them. Then calculate the average vertical angle and the average horizontal angle...and it is more likely that if anyone were to repeat these measurements, they would probably come closer to the averages of your measurements than to any one of the three individual measurements you took.

Keep in mind that as the day goes on, temperatures tend to rise..and heat causes most materials to expand and could throw things out of whack. Also, over long distances, heat shimmer can make it difficult to accurately sight on the target even with magnification of the telescope. So shading the instrument and planning your work earlier in the day when temperatures are cooler can also factor into the precision of your measurements
