Civil Engineering MCQs with Solution difficulty level 1

Question 1. (Force Analysis)

In order to determine the effects of a force acting on body, we must know:

Previously Asked in : HPSSSC JE 11.04.2021 ||

Its magnitude and direction of the line along which it acts.

Its nature (whether push or pull)

Point through which it acts on the body.

All of these

Detailed Explanation :

Concept:

For finding/determining the effect of a force acting on a point, we must know the following properties of force:

1. the magnitude of the force.
2. line of action of the force.
3. nature of the force, i. e., whether the force is push or pull.

Key Points

Magnitude:

This refers to the strength or intensity of the force, often measured in Newtons (N). 

Direction:

This specifies the orientation of the force, indicating which way it’s acting (e.g., North, West, at a specific angle). 

Point of Application:

This identifies the specific location on the body where the force is applied. 

Nature of the Force:

This clarifies whether the force is a push or a pull, which can affect the type of stress or strain exerted on the body.
