APSC AE CE Paper 1 Mock Test - 10 - Civil Engineering (CE) MCQ

Concept:

The yield of a well means the discharge from the well excavated through the given aquifer

Q = nv_a A = KiA

where,

n = porosity

v_a = the actual flow velocity of groundwater

A = the area of the aquifer opening onto the wells

K = the permeability of the soil

From the above relation, we can say that yield of a well (Q) is directly proportional to flow velocity, area of aquifer and permeability of soil.

The clear horizontal distance between two supports of an arch is called a span.

The exterior curved surface of the arch is called the extrados.

Hence the correct answer is option B.

Overhead expenses are all costs on the income statement except for direct labour, direct materials, and directexpenses. Overhead expenses include accounting fees, advertising, insurance, interest, legal fees, labor burden, rent, repairs, supplies, taxes, telephone bills, travel expenditures, and utilities.

IS : 3101 — Aluminium collapsible tubes.
IS : 3102 — Classification of burnt clay brick.
IS : 3495 — Method of test of burnt clay brick.
IS : 3496 — Specification for dobby lags and pegs.

Granite, basalt and traps are the igneous rock Granite cools above earth surface Basalt and traps cools below earth surface.

Hence the option D is correct.

It has a gain of strength beyond 28 days.

The quantum of increase depends on the grade and type of cement curing and environmental conditions. The design should be based on 28 days characteristic strength of concrete unless there is evidence to justify a higher strength for is a piece of evidence to justify a higher strength for a particular due to age.

Hence the option D is correct.

Hence the option C is correct.

A problem is rarely solved without one section of stair passing beneath another or under a landing. In those cases, one must be certain that stairs will not bump his or her head. The minimum headroom of all parts of a stairway must not be less than 80 inches (203.2 cm). It is measured vertically from a tread nosing, floor surface, or landing.

Hence the option B is correct.

Hence the option D is correct.

Hence the correct answer is option A.

Given:

• The degree of static indeterminacy (Dₛ) is 4/3 = 1.
• The formula for determining the number of hinges required for a plastic mechanism is: Dₛ₁ = 11 − Dₛ

Substituting the values: Dₛ₁ = 11 − 1 = 2

This leads to the correct conclusion that 2 hinges are required for the plastic mechanism to occur.

Thus, (option b) 2) is correct.

The maximum deflection of the tip of the cantilever beam with concentrated load P at the free end is Pl³/3EI

Hence the correct answer is option A.

Hence the correct answer is option C.

Thus, the road stones used in the construction should be sound enough to withstand the weathering action. The property of aggregates to withstand the adverse actions of weather may be called soundness.

For 30m chord,

Hence, the correct option is (B)

Given

Void ratio, e = 0.5

Discharge velocity = 6 × 10^-7 m/s

Specific Energy,

Where y = depth of the flow

v = velocity of the flow

g = acceleration due to gravity

In general, pyrolysis does not involve reactions with oxygen, water, or any other reagents.

Composting: Composting of refuse is a biological method of decomposing solid waste. If the organic materials excluding plastics, leather, and rubber are separated from the solid wastes and are subjected to decomposition either aerobically or anaerobically, the remaining end product is called compost or humus. The entire process involving both the separation and bacterial conversion of the organic solid wastes is known as Composting.

Incineration is one of the most effective methods of reducing the volume and weight of solid waste by burning it in a well-designed furnace.

A lower ratio leads to higher strength and durability but may make the mix difficult to work with and form.

The water-cement ratio is inversely proportional to the strength of concrete, lower water-cement ratio leads to an increase in bonds between the aggregates, cement, and sand.

As w/c increases quantity of cement in concrete reduces hence the availability of paste in concrete reduces. Poorer the paste higher the creep. therefore we can say that strength of concrete is inversely proportional to the creep.
