The levelling method used, to find the difference in elevation between two points, when it is
not possible to set up the level, midway between them is:

(^) Fly levelling (B) Precise Levelling
(C) Differential Levelling (D) Reciprocal Levelling

In Chain Surveying, correction for slope to be applied in a land _ surveyed
of length 100 m and level difference 1 m is:

(^) +1cm (B) -1 घण
(C) +0.cm (0) -9.5 का

Young’s Modulus of Elasticity for a perfectly rigid body is :
(A) Zero (B) Infinity
© Unity (D) 0.5

If a tensile stress of 60 kN/m? and a compressive stress of 50 kN/m? are acting at right angles
to each other on a piece of material then resultant stress on a plane, the normal of which
makes an angle 45° with 60 kN/m’ will be :

(A) 55 kN/m? (B) 5kN/m?

(C) 110 kN/m?* ൬) 10kN/m?

The resultant of two coplanar concurrent tensile forces :

0) 20KN inclined NE 45°

(1) 20 KN inclined NW 45° is
(^) zero (8) 10kN
)© 14.14kN (D) 28.28 kN

A force of 20 KN is acting through point B at an angle of 30° with line AB, 5 m long. Moment
at point A due to the force at B, is:

(A) 86.5kNm (B) 50kNm
(C) Zero (D) 100kNm

A simply supported Beam AB of span 6 m, acted upon by a concentrated upward force 10 kN
at 2 m from A and a clockwise moment 20 kNm at 2 m from B. The reactions at the supports
are:

(^) 10KN downward at A and zero at B
(2) 10KN upward at A and zero at B

(C) zero at Aand 10 kN upward at point B
(D) zero at Aand 10 kN downward at B
