Q3.Consider a bar of diameter ‘D’ embedded in a large concrete block as shown in the adjoining figure, with a pull out force P being applied. Let and be the bond strength (between the bar and concrete) and the tensile strength of the bar, respectively. If the block is held in position and it is assumed that the material of the block does not fail, which of the following options represents the maximum value of P?
Answer : Option CExplaination / Solution: No Explaination.
Q4.Consider two RCC beams, P and Q, each having the section 400 mm × 750 mm (effective depth, d = 750 mm) made with concrete having a τcmax = 2.1 N /mm2.
For the reinforcement provided and the grade of concrete used, it may be assumed
that the τc = 0.75 N/mm2. The design shear in beam P is 400 kN and in beam
Q is 750 kN. Considering the provisions of IS 456-2000, which of the following
statements is TRUE?
Answer : Option AExplaination / Solution: No Explaination.
Q5.The adjoining figure shows a schematic representation of a steel plate girder to
be used as a simply supported beam with a concentrated load. For stiffeners, PQ
(running between the top and bottom flanges) which of the following pairs of
statements will be TRUE?
Answer : Option BExplaination / Solution: No Explaination.
Q6.A singly under-reamed, m8 long, RCC pile (shown in the adjoining figure) weighing
20 kN with 350 mm shaft diameter and 750 mm under-ream diameter is installed
within stiff, saturated silty clay (undrained shear strength is 50 kPa, adhesion
factor is 0.3, and the applicable bearing capacity factor is 9) to counteract the
impact of soil swelling on a structure constructed above. Neglecting suction and
the contribution of the under-ream to the adhesive shaft capacity, what would be
the estimated ultimate tensile capacity (rounded off to the nearest integer value
of kN) of the pile?
Answer : Option BExplaination / Solution: No Explaination.
Q7.A rigid beam is hinged at one end and supported on linear elastic springs (both having
a stiffness of ‘k ’) at points ‘1’ and ‘2’, and an inclined load acts at ‘2’, as shown.
Which of the following options represents the deflections δ1 and δ2 at points ‘1’
and ‘2’?
Answer : Option BExplaination / Solution: No Explaination.
Q8.A rigid beam is hinged at one end and supported on linear elastic springs (both having a stiffness of ‘k ’) at points ‘1’ and ‘2’, and an inclined load acts at ‘2’, as shown.
If the load P equals 100 kN, which of the following options represents forces R1 and R2 is the springs at points ‘1’ and ‘2’?
Answer : Option DExplaination / Solution: No Explaination.
Q9.P, Q, R and S are four types of dangerous microbes recently found in a human
habitat. The area of each circle with its diameter printed in brackets represents
the growth of a single microbe surviving human immunity system within 24 hours
of entering the body. The danger to human beings varies proportionately with the
toxicity, potency and growth attributed to a microbe shown in the figure below:
A pharmaceutical company is contemplating the development of a vaccine against
the most dangerous microbe. Which microbe should the company target in its
first attempt?
Answer : Option AExplaination / Solution: No Explaination.
Q10.A container originally contains 10 litres of pure spirit. From this container 1 litre
of spirit is replaced with 1 litre of water. Subsequently, 1 litre of the mixture is
again replaced with 1 litre of water and this process is repeated one more time.
How much spirit is now left in the container?
Answer : Option DExplaination / Solution: No Explaination.
