Surveying_P-1_Theodolite Traversing

The operation of revolving the telescope in the horizontal plane about its vertical axis is called

• (a) Swinging
• (b) Transiting
• (c) Plunging
• (d) None of above

If N is the number of sides in a closed traverse, then the sum of interior angles should be equal to

• (a) (2N + 4) X 90
• (b) (2N * 4) X 90
• (c) (2N- 4) X 90
• (d) (N-4) X 90

If the whole circle bearing of a line is 270, its reduced bearing is

• N 90 W
• S 90 W
• W 90
• 90 W

Theodolite is used to measure

• horizontal distance
• vertical hight of object
• hori.and vertical angle
• All the above

Centring of instrument is carried out

• Alidade
• plumb bob
• sprit level
• none of these

Which is not the step of temporary adjustment of theodolite

• levelling
• focusing
• centring
• plate level test

which is not the part of levelling head

• trivet
• foot screws
• telescope
• tribrach

which are the fundamental lines of theodolite

• horizontal axis
• vertical axis
• tripod axis
• both(a) and (b)

By focusing of eye glass

• object canbe seen clearly
• cross hair canbe seen clearly
• both(a) and (b)
• none of these

Desired relationships among fundamental lines are

• Hori.axis should be perendicular to vertical axis
• axis of plate should be perendicular to vertical axis
• line of collimation should be perendicular to horizontal axis axis
• All the above
