Match the following Forces with their examples and select the correct answer using the codes given below:

Forces	Examples
a. Collinear forces	1. Forces on a rope in a tug of war
b. Coplanar concurrent forces	2. Forces on a rod resting against a wall
c. Non-coplanar concurrent forces	3. A tripod carrying a camera
d. Non-coplanar parallel forces	4. The weight of benches in a classroom

Explanation:

Collinear Forces

• Collinear forces act along the same line of action.

• Example: Forces on a rope in a tug of war, where all the forces are aligned along the rope.

Coplanar Concurrent Forces 

• These forces lie in the same plane and meet at a common point.

• Example: Forces on a rod resting against a wall, where normal reaction, weight, and friction act in one plane and meet at a point.

Additional InformationNon-Coplanar Concurrent Forces 

• These forces act in different planes but still intersect at a single point.

• Example: A tripod carrying a camera, where the three legs exert forces in different directions but all converge at the camera mount.

Non-Coplanar Parallel Forces → 4

• Forces that are parallel but not in the same plane.

• Example: The weight of benches in a classroom, where each bench’s weight acts vertically but at different locations and planes.
