Question

Just like the collinear force system for free body diagrams there is a system of the parallel forces.

(a) True

(b) False

The question was asked in my homework.

My doubt stems from Different Free Body Diagrams in section Equilibrium of a Rigid Body of Engineering Mechanics

Answer 1

The correct option is (a) True

For explanation I would say: There is a system so called the parallel system of the forces. This is another type of the forces. The simplification of this type of the forces is also very easy. This means that the forces in a certain direction is taken as positive and in the other direction is negative and hence the simplification is done.
