MCQ Civil Engineering

MCQ Civil Engineering 1

The slope deflection method requires the simultaneous solution of equations. The number of these simultaneous equations to be solved is equal to :

1. The degree of statical indeterminacy
2. The degree of kinematic indeterminacy
3. The number of joints in the structure
4. None of the above

Answer: C. The number of joints in the structure

Solution: Since slope and deflection (independent displacements) are the only variables in the slope deflection method, it can quickly determine the end moment if kinematic indeterminacy is low.

• The slope deflection method’s requirement for simultaneous equations to determine unknowns is equal to kinematic indeterminacy.
• The link between the bending moment, rotations, and deflections will be revealed by the slope deflection equation.
• In the slope deflection method, there are exactly as many simultaneous equations to be solved as there are joints in the structure.

MCQ Civil Engineering 2

For a plate of square edge, maximum size of a fillet weld is-

1. 1.5 mm less than the plate’s thickness
2. 1/2 of the thickness of the plate
3. Thickness of the plate itself
4. 1.5 mm more than the plate’s thickness

Answer: A. 1.5 mm less than the plate’s thickness.

Solution: Fillet welding refers to the process of joining two pieces of metal together whether they are at perpendicular or at an angle.

• When applying a fillet weld to a member’s square edge, the maximum size of the weld should be at least 1.5 mm smaller than the thickness of the edge.
• When applying a fillet weld to a rolled steel section’s round toe, the weld’s maximum size should not be greater than ¾  of the section’s toe thickness.
• When using a fillet weld for lap joints, the overlap of the connected elements must be at least five times as thick as the thinner section.

MCQ Civil Engineering 3

The water from a deep tube well should be treated for-

1. Pre-settling only
2. Coagulation and flocculation only
3. Filtration only
4. Disinfection only

Answer: D. Disinfection only

Solution: Water from a tube well is devoid of solids.

• After seepage through pores, water enters a deep tube well. It has less suspended particles as a result, but because it could also contain pathogens, disinfection is necessary.

MCQ Civil Engineering 4

The available sight distance on sag (or valley) curves is determined based on:

1. Design speed
2. Height of obstacle
3. Height of driver eye
4. Night-time driving conditions

Answer: D. Night-time driving conditions

Solution: A vertical curve having concavity upward or convexity downward is referred to as a valley curve. There is no restriction to sight distance at valley curve during day time but at night only source of visibility is with the help of the headlights in case of inadequate street lights.

MCQ Civil Engineering 5

It is discovered that the velocity varies as (1/r2) in a steady radial flow entering an intake, where r is the radial distance. The acceleration of the flow is proportional to:

1. 1/r⁵
2. 1/r³
3. 1/r⁴
4. 1/r

Answer: A. 1/r⁵

Solution:

For radial flow, acceleration = v²/r

Given velocity =  k/r²

Substituting the value of velocity into acceleration equation, acceleration =  k²/r⁵
