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

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.

Dry cell battery converts chemical energy into electricity. The chemical reaction produces electrons, which then collect at the negative terminal of the battery. When there is a connection between the positive and negative terminal, the electrons flow to the positive terminal.

‘‘सुरेन्द्र, भारती से चिट्ठी लिखवाता है।’’, वाक्य में प्रेरणार्थक क्रिया का भाव है।

प्रेरणार्थक क्रिया में कर्ता स्वयं कार्य न करके किसी दूसरे को कार्य करने के लिए प्रेरित करे, उसे प्रेरणार्थक क्रिया कहते हैं। प्रेरणार्थक क्रिया में दो कर्ता होते हैं-

प्रेरक कर्ता - प्रेरणा देने वाला।

प्रेरित कर्ता - जिसे प्रेरणा दी जाती है।

‘‘सुरेन्द्र, भारती से चिट्ठी लिखवाता है।’’ इस वाक्य में चिट्ठी भारती लिखती है, किन्तु चिट्ठी लिखने की प्रेरणा सुरेन्द्र देता है। अतः ‘लिखवाना’ क्रिया प्रेरणार्थक क्रिया है। इसमें प्रेरक कर्ता ‘सुरेन्द्र’ और प्रेरित कर्ता ‘भारती’ है।

'मनोज निकम्मा है इसलिए सब उससे घृणा करते हैं।' वाक्य में रेखांकित शब्द में समुच्चयबोधक अव्यय है।

संज्ञा या सर्वनाम की विशेषता बताने वाले शब्द विशेषण कहलाते है। उपर्युक्त वाक्य में रेखांकित पद ‘भयंकर’ विशेषण के रूप में प्रयुक्त हुआ है, जो ‘दुर्घटना’ शब्द की विशेषता बता रहा 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.

Fathometer is a depth finder that uses sound waves to determine the depth of water. It uses Echo sounding which is a type of sonar used to determine the depth of water by transmitting sound pulses into water.

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 be" verbs + Nominative case of personal pronoun or we can say subjective case pronoun will be used here.So, the correct answer is "We want the teacher to be he".

Refrain is to stay away or abstain.

Refute is to disprove.

Refuge is the state of being safe or sheltered from pursuit, danger, or difficulty.

Refuse is indicate that one is not willing to accept or grant (something offered or requested).

The edge of (something) refers to very close to doing something or of having some imminent event happen, especially that which is bad or disastrous.

Example : The company is still doing business, but ever since the recession hit, they've been teetering on the edge of closing down.

Printed data on a paper or other object is called hardcopy.

Nonvolatile (sometimes written as "non-volatile") storage (NVS) - also known as nonvolatile memory or nonvolatile random access memory (NVRAM) - is a form of static random access memory whose contents are saved when a computer is turned off or loses its external power source.

Device which consists of a keyboard and a monitor, and a connection to a full-fledged (intelligent) computer usually a server PC, minicomputer, or a mainframe computer. Dumb terminals have no 'intelligence' (data processing or number crunching power) and depend entirely on the computer (to which they are connected) for computations, data storage, and retrieval. Dumb terminals are used by airlines, banks, and other such firms for inputting data to, and recalling it from, the connected computer.

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.

Maximum deflection of a cantilever due to pure bending moment, M, at free and is (ML²/2EL).

Hence option D is correct.

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 units of Young's modulus in the English system are pounds per square inch (psi), and in the metric system newtons per square metre (N/m²).

For normal usage, the effective length in a given plane may be assumed from the table below assuming idealized conditions. No. Effectively held in position at both ends and restrained against rotation at one end. Effectively held in position at both ends but not restrained against rotation. Hence option B is correct.

The theoretical value of coefficient of contraction of a sharp edged orifice is 0.611.

The fresh sewage is generally alkaline in nature.

A flow in which quantity of liquid flowing per second is not constant, is called unsteady flow. Unsteady flow is a transient phenomenon. It may be in time become steady or zero flow. For example when a valve is closed at the discharge end of the pipeline. Thus, causing the velocity in the pipeline to decrease to zero.

According to the nature, pollutants can be classified into Non-degradable pollutants and Bio - degradable pollutants.

Non-degradable pollutants

Those pollutants which cannot be broken down into simpler, harmless substances in nature.

DDT, plastics, polythene, bags, insecticides, pesticides, mercury, lead, arsenic, metal articles like aluminum cans, synthetic fibers, glass objects, iron products and silver foils are nonbiodegradable pollutants. (Tables)

Bio-degradable pollutants

Those pollutants which can be broken down into simpler, harmless substances in nature.

Sewage waste, domestic waste, etc. are bio-degradable waste.

Sulphate attack on concrete is a chemical breakdown mechanism where sulphate ions attack components of the cement paste.

The compounds responsible for sulphate attack on concrete are water-soluble sulphate-containing salts, such as alkali-earth (calcium, magnesium) and alkali (sodium, potassium) sulphates that are capable of chemically reacting with components of concrete.

C₃A controls the effect of sulphate in cement.

Characteristics of contour line,

1. The horizontal distance between any two contour lines indicates the amount of slope and varies inversely on the amount of slope.
2. Closely spaced contour indicates steep slope ground.
3. Widely spaced contour indicates flat surface.
4. Equally spaced contour indicates uniform slope.
5. Irregular contours indicate uneven surface.

Hence option B is correct.

Coefficient of uniformity for well graded soil,

( C_u > 4 for gravels.

And C_u > 6 for sand ).

For poorly graded soil, C_u ≈ 1

The modulus of rigidity, also known as shear modulus, is defined as a material property with a value equal to the shear stress divided by the shear strain.

The ratio of beam depth to its width is recommended to be 1.5 to 2.

For initial estimate of a beam design,

The width of the beam is taken as 1 /30^th of the span.

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.
