Question

What is a collinear system of forces for the system of the fluid liquids?

(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 in an internship interview.

This interesting question is from Fluid Pressure in portion Centre of Gravity and Centroid of Engineering Mechanics

Answer 1

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

The explanation is: 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.
