Question

What is a collinear system of forces?

(a) The force system having all the forces parallel to each other

(b) The force system having all the forces perpendicular to each other

(c) The force system having all the forces emerging from a single point

(d) Forces cannot form a collinear system of forces, it is not possible

The question was asked by my school teacher while I was bunking the class.

The origin of the question is Simplification of a Force and Couple System topic in division Force System Resultants of Engineering Mechanics

Answer 1

Correct choice is (c) The force system having all the forces emerging from a single point

For explanation: The force system having all the forces emerging from a point is called the collinear system of force. This is a type of system of the force, which is easy in the simplification. This is because as the forces are the vector quantity, the vector math is applied and the simplification is done.
