Can a theodolite measure distances?

Yes, but it is an indirect process requiring two operators- or at least a fixed surveying target on which the surveyor aligns his Stadia wires ( popularily Cross hairs) There are different scales but a base-line of l00 feet and in some cases l00 power is increasingly standard. consulting a table and some number-juggling is needed to get the distance, and more importantly the Vertical rise and Fall ( gradient, up or down) The theodolite is better adapted to this type of surveying, than a mere ( range finder)- which is can be used for- but with some shifting of tactics and technique. The basic tables in the technical manuals assume a base line distance of l00 feet, then there are angles, etc.

Do you have to put down steel when concreting a driveway?

No. Most redi-mix companies have an additive the introduce to the concrete at time of mixing. It is called "Fiber Mesh". It is fiberglass hairs that replace the use of rebar. Generally it is one bag per yard of mixed concrete. For a driveway it would be highly recommended to use at least wire mesh due to the weight they must withstand.


Where you can use optical fiber?

optical fibres work on the principle of total internal reflection.that is a long concept but easily available.because of this T.I.R the light transmitted through the wires is very small.so it can travel a longer distance(not necessarily rectilinear).so it finda application in medical surgery to get a view of the organs by inserting optical fibres through the wind pipe.it is also used to carry light to those materials that cannot be placed inside a spectroscope directly.they are also used for decoration purpose.the lamps with glowing hairs are good examples.
