Mechanics Questions and Answers

Mechanics MCQ 1

Q1. Which of the following is a branch of mechanics?

1. Statics and kinetics
2. Statics and dynamics
3. Kinematics and dynamics
4.  Kinetics and kinematics

Answer: 1. Statics and dynamics

 Statics and dynamics is the branch of mechanics.

Solution:

Statics and dynamics are the two subfields of mechanics. The study of bodies at rest is the focus of Statics. The study of bodies in motion is the subject of dynamics.

Mechanics MCQ 2

Q2. Which of the following is the basic law for mechanics?

1.  Newton’s law of viscosity
2.  Parallelogram law
3.  Newton’s laws of motion
4.  Hooke’s law

Answer: 1. Newton’s laws of motion

Newton’s laws of motion is the basic law for mechanics.

Solution:

Newton's laws of motion is the fundamental law for engineering mechanics. The first law, second law, and third law of Newton are frequently utilized to resolve problems with mechanical aspects.

Mechanics MCQ 3

Q3. Which of the following is termed as an action of pull or push of a body at rest or motion?

1.  Torque
2.  Momentum
3.  Work
4. Force

Answer: 4. Force

An action of pull or push of a body at rest or motion is termed as force.

Solution:

A force is defined as the pull or push of a body while it is at rest or in motion. A body moves when an outside force acts on it. Force is this outside factor.

Mechanics MCQ 4

Q4. Which of the following is the condition for the three-force theorem in mechanics?

1.  The force system should be in equilibrium only
2.  The force systems should be non-coplanar
3.  The system should be co-planar, parallel
4.  The force system should be in equilibrium, co-planar, concurrent, or parallel

Answer: 4. The force system should be in equilibrium, co-planar, concurrent, or parallel

The force system should be in equilibrium, co-planar, concurrent, or parallel is the condition for the three-force theorem in mechanics.

Solution:

According to the three force theorem, when three forces act on a body, the force systems are in equilibrium, coplanar, and either concurrent or parallel.

Mechanics MCQ 5

Q5. According to which of the following laws of mechanics a body remains/continue in its state of rest or motion until it is disturbed by an external agent?

1.  Newton’s first law of motion
2. Newton’s second law of motion
3.  Newton’s third law of motion
4.  Superposition law

Answer: 1. Newton’s first law of motion

According to Newton’s first law of motion a body remains/continue in its state of rest or motion until it is disturbed by an external agent.

Solution:

According to Newton's first law, if a body is at rest or moving along a straight route at a constant speed, it will stay at rest or keep moving until acted upon by a force.
