SSC JE 2019-20: Technical Quiz 79 for ESE & GATE CE Exams

Question 1

A singly reinforced rectangular concrete beam has a width of 150 mm and effective depth of 330 mm. The characteristic compressive strength of concrete is 20 MPa and the tensile strength of steel is 415 MPa. Adopt the stress block for concrete as per IS 456-2000 and take the limiting value of depth of neutral axis as 0.48 times the effective depth of the beam for considering as a balanced section. What is the likely approximation for the limiting value of the moment of resistance of the beam?

Question 2

A rectangular 230 mm × 350 mm beam is (effective depth). The factored shear force acting at a section is 80 kN. If the permissible shear stress in concrete is 0 ·25 MPa, the design shear force is nearly

Question 3

Consider the following statements:
1) Functions of reinforcements in reinforced soil and in reinforced concrete are comparable.
2) The design of a geotextile reinforced wall is similar in principle to that of a reinforced earth wall.
Which of the above statements is/are correct?

Question 4

Footings shall be designed to sustain the
1) Applied loads
2) Moments and forces under relatable loading conditions
3) Induced reactions

Question 5

Which of the following measures are relevantly considered for earthquake loading and lateral stability of tall buildings?
1) Minimizing gravity loads
2) Adding masses at floor levels
3) Ensuring ductility at the locations of maximum moments
4) Providing shear walls
5) Providing basement
Select the correct answer using the code given below:

Question 6

As compared to the working stress method of design, the limit state method of design premises that the concrete can admit

Question 7

As per IS 456 – 2000, the maximum permissible shear stress,

is based on

Question 8

The purpose of work-break-down structure in project planning is mainly to
1) Facilitate and improve the decision-making on procurement of resources
2) Relate activities under particular trade specializations to help in organizing for project staff
3) Co-ordinate regarding milestone events across trade specializations to improve the synergy between the trades

Question 9

Which of the following statements is/are correct?
1) An activity is in between two node numbers, which need not be in an increasing order in the activity progress sequence.
2) The length of the arrow in a network has certain significance.
3) Concurrent activities are mutually independent and can possibly be taken up simultaneously.

Question 10

A tractor has a permissible loaded speed of 200 m/minute, which can increase by 25% when the load is removed/deposited. Generally, it is operated at 80% of the permissible speed (loaded unloaded). It works at a location where haul distance is 120 m. Rest allowance per round-trip is taken as 50 seconds on an average. Fixed time per trip, for loading and unloading and turnaround, etc., is 30 seconds.
What is its effective cycle time?
