What is the purpose of the Two Theodolites Method?
Think about the challenges faced in measuring distances in civil works.
True or False: Deflection angles are used to adjust for straight line measurements.
Recall the application of angles in curve settings.
In setting out a curve with a radius of 100m, if the first deflection angle calculated is 12° and chord length is 30m, what would be the setting for the theodolite at T₁?
Utilize the relationship between angle, radius, and chord lengths to set accurately.
If the two points established on a curve appear misaligned from the intended design after initial setup, outline the steps to rectify this situation.
Re-evaluating each point’s positioning may clarify the adjustments required.
