Question

(a) A 30 m long steel tape is supported at the ends. Find the normal tension for the tape with the following data : Cross section of the tape = $4 \text{ mm}^2$. Weight of tape material = $0.0786 \text{ N/mm}^2$, $\text{E} = 200 \text{ GN/m}^2$, and the pull at which the tape is standardized is $100 \text{ N}$. (5)

(b) Explain the following terms :

(i) Vertical axis

(ii) Line of collimation

(iii) Face left observation

(iv) Changing face

(v) Transiting. (5)

(c) Differentiate between the followings :

(i) Cumulative and compensating errors

(ii) Perpendicular and oblique offsets

(iii) Direct and indirect method of chaining

(iv) Linear and Angular measurements. (8)
