Question
As per plan, the distance between two telephone poles is 356.35 meters. If the location of one is known in the field and the second is to be laid with a 100 m tape known to be 0.02 meter too long, along an average ground slope of 1%. Determine the actual length to be laid along the ground surface.
Given: | |
Nominal Tape Length | L1 |
Required Distance to be Laid out | Di |
correction due incorrect tape length | Ci |
Ground slope | S |
Solution | |
correction per tape length (correction 100-m length) | |
incorrect tape length | Ci |
slope correction (approximate method) | CSL |
cumulative correction per tape length (all sources of tape corrections) | C |
total correction (correction for Di) | tot C |
Tape too long (+) or too short (-)? write the sign only | |
Is the total correction to be added or to be subtracted? | |
Correct Distance to be laid out | DC |
Expert Solution
Step 1: Mention the given data
