# Design of RC Structures Questions and Answers – Nominal Shear Stress

This set of Design of RC Structures Multiple Choice Questions & Answers (MCQs) focuses on “Nominal Shear Stress”.

1. At which point does bending stress is maximum?
a) Centroid
b) Extreme Fibres
c) End Points
d) Centre of the beam
View Answer

Answer: b
Explanation: Bending stress is maximum at the extreme fibres because of the bending moment having in maximum magnitude at that point.

2. At what point does shear stress is maximum in the beam?
a) Centroidal Axis
b) Extreme Fibres
c) End Points
d) Centre of the beam
View Answer

Answer: a
Explanation: Shear stress is maximum at the Centroidal axis because of the shear having in maximum magnitude at that point.

3. At which point does bending stress is zero in a beam
a) Centroidal Axis
b) Extreme Fibres
c) End Points
d) Centre of the beam
View Answer

Answer: a
Explanation: Bending stress is zero at Centroidal axis because of zero bending moment at that point.

4. At which point does shear stress is zero in a beam?
a) Centroid
b) Extreme Fibres
c) End Points
d) Centre of the beam
View Answer

Answer: b
Explanation: Shear stress is zero at extreme fibres because of zero shear at that point.

5. While designing a beam, what points are considered from the following?
a) Shear force
b) Bending moment
c) Both A and B
d) Neither A nor B
View Answer

Answer: c
Explanation: Both shear force and bending moment is considered while designing a beam because both acts as a loading and variable in it.

6. Why is slump cone test performed in the concrete?
a) To determine strength
b) To determine workability
c) To determine toughness
d) To find permeability
View Answer

Answer: b
Explanation: Slump cone test is used to determine the workability of concrete. It helps to find the magnitude and nature of slump that whether it is true, shear or collapse.

7. What is the ratio of bond stress for high yield stress bars to plain bars?
a) 1.2
b) 1.4
c) 1.6
d) 1.8
View Answer

Answer: b
Explanation: According to Indian Standard’s code, the ratio of bond stress for high yield stress bars to plain bars is 1.4.

8. Which of the following is in the least amount in white cement?
a) Lime
b) Silica
c) Aluminum Oxide
d) Iron Oxide
View Answer

Answer: d
Explanation: Iron Oxide is in least amount in white cement that is why it is low in strength.

9. What is the maximum size of fine aggregate?
a) 2mm
b) 4.75mm
c) 5mm
d) 10mm
View Answer

Answer: b
Explanation: Maximum size of fine aggregate is 4.75mm because when it crosse this size, it becomes coarse aggregate.

10. What is the main ingredient of OPC in the following?
a) Lime
b) Iron Oxide
c) Silica
d) Alumina
View Answer

Answer: a
Explanation: Lime is the main ingredient of ordinary Portland cement. It helps the cement to become a binding material.
