Please tell me how to estimate height of flag pole.?

Question

I need to purchase rope and do not know how much to buy and pole is too tall to reach and I cannot climb it and if I take off the rope that is on it then I can't get new one back in pulley at top.

Answer 1

1- Attach the end of a ( fifty-foot ) tape measure to the clip which holds the top of flag.
2- Raise it to the top.
3- Read the tape.
4- Double the number and add a little.

Answer 2

get a 12 in ruler. or a meter stick mark the existing rope with a bright colored tape move the rope all the way up until the first mark you made reaches the top (where the flag would usually stay) . count how many marks youve made multiply it with whatever stick you used to mark it (12 inch rule or meter stick).i.e. 10 marks using a meterstick would mean 10 meters multiply by 2.2 would mean you need at least 22mtrs which is enough so you have some allowance. There you have it a very near approximation of the rope lenght of the flagpole...One more thing, lets say you counted 9 and a half ..then thats 9.5 meters using the meterstick..( whats the 2.2 for??.you need to multiply it by 2 to get the full length of the rope going around the pole's length. the 0.2 is an allowance factor, thus giving you 2.2.)

Answer 3

Get some cardboard and a ruler.

Mark a 12" line (or 24" line), then perpendicular (90 degrees) to that and from one end of the line, mark another line the same length (the longer the line, the more accurate your height measurement will be).

Draw the diagonal connecting the ends of the lines to form a triangle.

Cut out the triangle, making sure the diagonal line is perfectly straight (the first 2 lines can be rough cut).

Take your triangle and a level and walk away from the base of the flagpole. As you keep the base of the triangle level, sight up the diagonal until you see the top of the pole.

Measure the distance from where you are to the base of the pole, then don't forget to add the height from the ground to your eye-balls. Add another 10% or 20% of that length, just to be 'sure'.

Hi: there are two way you can do this: The simplest is to get the following items: a protractor, a piece of long string, a something for a weight, a scientific Calculator with trig functions, and a tape measure and a friend to help read the measurement of the protractor . Okay. Use the tape measure, and measure 10 feet from the flagpole, tie one end of the string with the weight and tie the other to the center of the protractor, at the 10 foot mark on the ground let the weighted end of the string fall toward ground ( but not touching the ground itself ) Now with the flat end of the protractor ( from one end of it to the other) sight the top the flagpole and when you do; have your friend read off the angle made by the weighted end of the string and the round part of the protractor . Write that angle down and use the scientific calculator and do the following: Input your angle and hit the Tan(x) button and multiply it by 10 , Your flagpole height will be the answer in feet the other way is to use a standard 12" ruler and go any distance away from the flagpole and hold up your ruler at eye level and find some convenient object ( such as a building outcropping or wall) ( in this cause a wall) put the zero end of the ruler on it and find out how far away the flagpole is away from the zero end of the ruler by reading the marking off the ruler . Write this value down (I'll call it A) . Using the same point as before tilt the ruler and find what marks on the rule touch the top of the flagpole write this value down ( I'll call it C). Now use a tape measure, measure the distance from that point ( in this cause the wall) to the flagpole, Write it down ( I'll call it D) Okay do the following : input the A value, square it; write it down or store it in the calulator memory. then input the C value, square it, then subtact the C value with the A value in memory or what the squared value you wrote for it was (or C^2- A^2) . press the " = " key than press the Square root key or press the "^" key and input .5 and press the " = " key. write down the answer ( I'll call it B) input the B value and divided it by the C value, press the " = " key and multiply it by the D value, press the " = " key and you should have your flagpole height Hope this helps

Answer 5

Well, measure the shadow first then measure you and your shadow. Then make a proportion.

Shadow = Shadow
_______ __________

Height = Height

Then cross multiply and divide to get the height of the pole (you shoudl put and variable for the height of the pole)

Answer 6

Compare the length of the shadow of the pole to the shadow of a stick.

Shadow stick / height stick = shadow pole / height pole
