Question

In the screw collinear forces act, 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

This question was posed to me during an interview for a job.

I need to ask this question from Frictional Forces on Screws topic in portion Friction of Engineering Mechanics

Answer 1

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

The best I can explain: 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.
