MP Vyapam Sub Engineer Civil Mock Test - 5 - Civil Engineering (CE) MCQ

Algae are plants, the body of the zinc does not divide into heavy, stem and leaves. Algae are aquatic plants, which can be found in small ponds from the sea. Some algae also live in the roots of plants, for example, 'cycos' inhabit 'nostock' in 'Anabina' and 'Anthoseros' (Bryophyte) in the roots of pies. Some algae cooperate with fungi. The study of algae is called 'phycology'.

The gravitational force is always attractive. It acts between any two pieces of matter in the Universe since mass is its source.

The electromagnetic force can be attractive or repulsive and acts only between pieces of matter carrying an electrical charge.

Urdu-i-Mualla, Al-Hilal, Al-Balagh, Zamindar, Comrade and Hamdard were owned by heavyweight Muslims politicians who believed in journalism to extend their political causes among the educated Muslims.

'संज्ञा’ पद से निर्मित उपयुक्त विशेषण ‘कृपालु’ ( कृपा+ आलू ) शब्द होगा। जहाँ कृपा शब्द संज्ञा है।

कोई-कोई धातु प्रयोग के अनुसार सकर्मक और अकर्मक, दोनों होते हैं। इनको उभयविध धातु कहते हैं। ‘खेल-तमाशे की चीजें देखकर भोले-भाले आदमियों का जी ललचाता है।’ वाक्य में क्रिया के भाव से ‘उभयविध धातु’ क्रिया का पता चलता है।

संज्ञा या सर्वनाम का क्रिया से सम्बन्ध जिस रूप से जाना जाए, उसे कारक कहते हैं। कारक यह इंगित करता है कि वाक्य में संज्ञा या सर्वनाम का काम क्या है।

Systemic circulation carries oxygenated blood from the left ventricle, through the arteries, to the capillaries in the tissues of the body. From the tissue capillaries, the deoxygenated blood returns through a system of veins to the right atrium of the heart.

Greenhouse gases that occur both naturally as well as from human activities include water vapor, carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O). They cause pollution in atmosphere. But oxygen is not a green-house gas.

A Barr body is the inactive X chromosome in a female somatic cell in those species in which sex is determined by the presence of the Y or W chromosome rather than the diploidy of X, or Z.

Charlatan: a person falsely claiming to have a special knowledge or skill.

Exponent: someone who is very good at a particular skill or activity and is an example to other people.

Swindler: one who cheats a person out of money or other assets.

Hoaxer: a person who trick or deceive someone by means of a hoax.

Cajole: persuade someone.

‘To get cold feet’ is an idiom which means to become frightened to do something. Thus, the correct option is (a).

Example: Do you still want to do this parachute jump or are you getting cold feet?

To find the speed of the bird in km/h.
Bird flying in the North at an angle of elevation = 30°
After 2 minutes,
Bird flying in the South at an angle of elevation = 60°
Bird flies in a straight line at a height = 50√3m
From the figure,
AB = CD = height = 50√3m
InΔOAB,
tan 30° = AB/OA

OA = 50√3 x √3
 = 50 x 3 = 150
OA = 150m
InΔOCD,
tan 60° = CD/OC

OC = 50
OC = 50m
The total distance, AC = OA + OC
= 150 + 50
= 200
AC = 200m
Where, AC = BD = 200m.
Speed of the bird = 200/2 = 100
= 100m/min
To convert m/min to km/hr
Speed of the bird = 100/1000 x 60
= 6km/h
Therefore, speed of the bird is = 6km/h.

Total marks of 8 subject = 87 x 8 = 696
first max- second max = 2
After replacing both max marks = 6 x 85 = 510
Then sum of both max marks = 696 - 510 = 186
So maximum marks = (186+2)/2 = 94

By using bundled bars, concrete can be compacted properly and also the large of reinforcement can be made to concentrate at a point resulting in the increase of effective depth. Hence option C is correct.

Irrigation canals are generally aligned on Ridge line.

Hence option A is correct.

Permanent wilting point (PWP) or wilting point (WP) is defined as the minimal amount of water in the soil that the plant requires not to wilt. If the soil water content decreases to this or any lower point a plant wilts and can no longer recover its turgidity when placed in a saturated atmosphere for 12 hours.

This Regulation does not provide design formulas nor permissible stresses or strains, but requires the adequacy of the design to be established by appropriate calculations and demonstrated by cylinders being capable of consistently passing the materials, design qualification, production and batch tests specified in this Regulation, and also know as working stress.

The correct answer is H^5/2.

Hence option C is correct.

The deflection including the effect of temperature, creep and shrinkage occurring after the erection of partitions and the application of finishes should not normally exceed span/350 whichever is less, creep is directly proportional to the stresses but above this value it increases more rapidly.

As per the hydrostatic law, the rate of increase of pressure in the vertically downward direction must be equal to the specific weight of the fluid at that point.

Grading of the aggregates has a great effect on the workability, uniformity, and finishing qualities of concrete. Different grades of aggregate would lead to a significant reduction in void ratio resulting in more compact, dense and high strength concrete.

Curing: It is the process of hardening the concrete mixes by keeping its surface moist for a certain period, in order to enable the concrete to gain more strength.

Mixing is the process of mixing different ingredients of the concrete mix e.g. aggregates, binding materials, water, admixtures, etc.

Batching is the process, in which the quantity or proportion of materials like cement, aggregates, water, etc. are measured on the basis of weight or volume to prepare the concrete mix. It is preferably done by the weighing method so to avoid the problem of bulking of sand.

∴ Batching refers to the process of proper and accurate measurement of concrete ingredients for uniformity of proportion.

Controlled concrete: A concrete mix which is designed on the basis of test of the strength conducted in the laboratory on the trial mixture of cement and aggregate to be actually used in the construction is termed as controlled concrete.

Ordinary concrete is designed by volume and is used as PCC and not for structural related works, while Controlled concrete is designed by weight and designed to get a controlled mix, strength and durability as per structural requirements.

Unless or otherwise specified specific gravity values reported shall be based on water at 27°C. So the specific gravity at 27°C = K Sp. gravity at Tx°C. The specific gravity of the soil particles lie with in the range of 2.65 to 2.85.

A maximum number of vehicles can be parked at 90° parking angle.

This 90° parking angle causes obstruction to the road traffic particularly if the road width is less. But, it can accommodate the maximum number of vehicles for a given kerb length.

Velocity due to the depth of channel,
V = √g y
= √9.81 x 1
= 3.132 m /sec
Upstream velocity + flow velocity = velocity due to the depth of channel
Upstream velocity = 3.132–2 = 1.132 m /sec

Representative fractions are a unit-less relation between one “unit” on the map and however many “units” of the same type on the ground.

Representative fraction = 10 cm / 20 km

» R.F = 10 /20 x 1000 x 100

= 10 / 2000000

= 1 / 200000.

As per IS 456:2000

The grade of concrete M 150 means that compressive strength of a 15 cm cube after 28 days, is 150 kg/cm².

Ideal water cement ratio for general works is 0.45. During machine mixing, it can be in the range of 0.4-0.5. Hand mixing is done by labourers and maximum 0.6 can be allowed.

Aggregates used are sand, gravel or crushed stones. These have high compressive strength. Concrete is strong in compression and weak in tension due to this reason.

Retarders are used to slow down the initial rate of hydration and extend the initial setting time. It is therefore used to grout deep oil wells, transport RMC (Ready Made Concrete) and avoid cold joints. Accelerator is used for first 3 options.
