A surveyor made an error during the survey of a project which is associated with his skills and vigilance. Which type of error this surveyor has committed?

A. Blunders
B. Random errors
C. Systematic errors
D. Constant errors

Detailed Solution for Mock Test: SSC JE Civil Engineering (CE)- 10 - Question 126 Systematic errors: A systematic error is an error that, under the same conditions, will always be of the same shape and size.

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.

Mock Test: SSC JE Civil Engineering (CE)- 10 - Question 127

Which of the following statement is correct?

A. The error in measured length due to bad ranging is compensating error.
B. If the chain used in measuring a distance is too short, the error is a positive error
C. The error in measured length due to careless holding of the chain is a cumulative error
D. When the pull applied while measuring with the tape is more than the standard pull for that tape, the error in measured length is positive

Detailed Solution for Mock Test: SSC JE Civil Engineering (CE)- 10 - Question 127

The error in measured length due to bad ranging is always positive as the measured value due to bad ranging is always greater than the actual value.
As the error in measured length due to the careless holding of the chain is an accidental error and accidental errors as obvious compensating in nature.
Correction for Pull (C_p):

Where,

P = Pull applied during measurement

P_o = Standard Pull

L = length of the tape

E = Young’s modulus of elasticity

So, when P > P_o, the corrective will be positive, and the error will therefore be negative.

If the chain used in measuring a distance is too short, the error will be positive, and correction will be negative and vice versa.

A. Always operates in submerged condition
B. Converts pressure head into velocity with the help of vanes
C. Operates by initial complete conversion to kinetic energy
D. Operates by initial complete conversion to potential energy

Detailed Solution for Mock Test: SSC JE Civil Engineering (CE)- 10 - Question 139 In the Impulse Turbine, the available hydraulic energy is first converted into kinetic energy by means of an efficient nozzle.

The high-velocity jet issuing from the nozzle then strikes a series of suitably shaped buckets fixed around the rim of a wheel.

H⁺ = concentration of H⁺ ions (mg/l)

If, pH < 7,="" it="" is="" reported="" as="" />

pH > 7, it is reported as basic

pH = 7, it is reported as neutral

This implies, the lesser the pH value, the stronger the acid is.

So, among 2 and 5,

pH = 2 represents stronger acid.

The period of cleaning of a slow sand filter is usually:

A. 30 days to 90 days
B. 120 days to 180 days
C. 90 days to 120 days
D. 15 days to 30 days

Detailed Solution for Mock Test: SSC JE Civil Engineering (CE)- 10 - Question 155 Slow sand filter: They consist of fine sand, supported by gravel. They capture particles near the surface of the bed and are usually cleaned by scraping away the top layer of sand that contains the particles.

Cleaning:

For cleaning, the top layer of sand is scrapped and 1.5 to 3 cm of sand is removed in each cleaning.
The frequency of cleaning is 1 to 3 months.
The rate of filtration is 100-200 l/hr/m2 of filter area.
It is used for smaller plants in villages.

Rapid sand Filter: They consist of larger sand grains supported by gravel and capture particles throughout the bed. They are cleaned by backwashing water through the bed to 'lift out' the particles.

Cleaning:

Cleaning of the filter can also be done using surface wash but it should be accompanied by backwash.
Washing period = 24 to 48 hrs.

Mock Test: SSC JE Civil Engineering (CE)- 10 - Question 160

The net area of round bars to resist the tension, is the area of the cross-section at

A. mid-section
B. the root of the thread
C. difference of mid-section and root of the thread
D. None of these

Detailed Solution for Mock Test: SSC JE Civil Engineering (CE)- 10 - Question 160 The net tensile area at threads may be taken as the area corresponding to the root diameter at the thread.

Note: The shearing of rods can take place in the threaded portion of the rod and so the area at the root of the threads, also called the tensile stress area. Since threads can occur in the shear plane, the area for resisting shear should normally be taken as the net tensile stress area, ATnet, of the bars.

Factored load-carrying capacity of the weld,

P = permissible shear stress in the weld(f_y) × effective area of the weld the effective area of the weld = effective length of the weld(L_eff)× throat thickness(T_t)

Mock Test: SSC JE Civil Engineering (CE)- 10 - Question 166

The main objective of compaction of concrete is:

A. To incorporate air voids
B. To provide intimate contact between the concrete and embedded materials
C. To make the concrete less dense
D. To increase the permeability of the concrete

Detailed Solution for Mock Test: SSC JE Civil Engineering (CE)- 10 - Question 166 Compaction of concrete is the process adopted for expelling the entrapped air as far as possible from the concrete to achieve the highest possible density of the compacted mass.

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
