Quadrantal circle bearing = N 25^∘W

Whole circle bearing =360^∘−25^∘=335^∘

Hence, the correct option is (c).

The head loss in turbulent flow in a pipe varies approximately as the square of the velocity.

(D_se = 6 - 3 = 3)

And white lead for wooden surfaces.

G= Specific gravity

e= void ratio

1) Dead load and imposed load=180,

2) with wind and earthquake action=250,

3) with lateral torsion buckling-300.

Now, the Tension member

1) With the reversal of the direct stress other than wind or earthquake -180.

2) Reversal of the stress with wind and earthquake-350.

3) Member always under tension other than pre-tensioned member-400.

In volume batching of concrete boxes of size:  300 X 380 X 380 are used

For doubly reinforced section, tension reinforcement is designed for stress of 0.87fy but for compression reinforcement a lower stress must be used. The reason being that steel may buckle between shear stirrups under compressive stresses. And hence doubly reinforced beam is considered less economical because compressive steel is under stressed.

Hence the option D is correct.

Hence the option C is correct.

Hence the correct answer is option B.

Hence the correct answer is option C.

The hollow circular rod has a shape factor of 1.27

Rectangle and square have a shape factor of 1.5

Hence the correct answer is option (c).

Hence the correct answer is option D.

Hence the correct answer is option C.

• Bend

• Junction

• Change of gradient

Hence, the correct option is (C)

Defects arise in timber during its seasoning are

Bow: Curvature of timber in the direction of its length is known as Bow.

Cup: Curvature in the transverse direction of timber is known as a cup.

Twist: It is the spiral distortion in the direction of timber.

Spring: Curvature of the timber in its own plane

Note: While Upsets and Rind galls are the defects arises due to natural forces.

While Upsets: (crushing and compression)

Rind galls : (Improper cutting of branches)

Hence, the correct option is (A)

or shear force = 0

Hence, the correct option is (D).

A systematic error always follows some definite mathematical or physical law and a correction can be determined and applied.

Such errors are of constant character and are regarded as positive or negative according to as they make the result too great or too small.

Blunders: A blunder (or gross error) is a significant, unpredictable mistake caused by human error that often leads to large discrepancies.

Blunders are typically the result of carelessness, miscommunication, fatigue, or poor judgment. Examples of common blunders are:

i) Improperly leveling of the surveying instrument.

ii) Setting up the instrument or target over the wrong control point.

Random (or accidental) errors are not directly related to the conditions or circumstances of the observation.

For a single measurement or a series of measurements, the error remains after all possible systematic errors and blunders have been eliminated.

Random errors are unpredictable and are often caused by factors beyond the control of the surveyor. Their occurrence, magnitude, and direction (positive or negative) cannot be predicted.

• Compaction improves the fluidity of concrete and with the reduction of internal friction, packing of coarse aggregates take place

• A well-compacted concrete is free of the loose pockets and air bubbles of entrapped air

• The main purpose of compaction of concrete is to get a dense mass without voids, to get the concrete to surround all reinforcement, and to fill all corners i.e. to provide intimate contact between the concrete and embedded materials
