This set of Design of RC Structures Multiple Choice Questions & Answers (MCQs) focuses on “Limiting Shear Stress”.
1. Stress is ______
a) Internal resistive force
b) Force
c) External force
d) Axial force
View Answer
Explanation: Stress is the resistance provided by the structure to the force applied to it.
2. Which of the following is not a basic stress?
a) Volumetric Stress
b) Shear Stress
c) Compressive Stress
d) Tensile Stress
View Answer
Explanation: When the deforming forces loaded in all directions of an object and it deforms in all directions it is called volumetric stress.
3. Select the most elastic material from the following.
a) Rubber
b) Wood
c) Steel
d) Glass
View Answer
Explanation: Steel is the most elastic material from the following, that is why it is used for reinforcement in concrete.
4. Which of the following condition is true for volume strain?
a) Increase in length ÷ Original length
b) Original length ÷ Increase in length
c) Change in volume ÷ Original Volume
d) Decrease in length ÷ Original length
View Answer
Explanation: The volumetric strain is the ration between the change in the volume and its original volume.
5. If a material has same properties in all direction than it is _____
a) Elastic
b) Plastic
c) Homogenous
d) Isotropic
View Answer
Explanation: Isotropic material means a material having identical values of a property in all directions. e.g. Glass, Metal, etc.
6. Hook’s Law is valid only within ______
a) Plastic Limit
b) Fracture
c) Elastic Limit
d) Anywhere
View Answer
Explanation: Hook’s Law is the law which states that, the force needed to extend or compress a spring by a distance is proportional to that distance.
7. Which of the following property is true for brittle material?
a) Plastic Nature
b) Elastic Nature
c) Homogenous
d) Conductors
View Answer
Explanation: Brittle material is the material which has the tendency to break and has the ability to fracture.
8. What is the SI unit of strain?
a) m/s
b) cm/s
c) cm/s2
d) No unit
View Answer
Explanation: The strain has no SI unit. It is a ratio.
9. Which of the following results to plastic deformation?
a) Slip
b) Fracture
c) Elastic
d) Break
View Answer
Explanation: Plastic nature is the property by virtue of which, the material stays in the shape after a force is applied to it.
