Question

A system of two or more forces whose lines of action ALL intersect at a common point. However, all of the individual vectors might not actually be in contact with the common point.

a) Concurrent forces
b) Non-concurrent forces
c) Coplanar forces
d) Collinear forces

Answer 1

Concurrent forces are a system where two or more forces intersect at a common point. When two forces are in equilibrium on a point, they have equal magnitudes but opposite directions.

Step-by-step explanation:

The student is asking about a system of two or more forces whose lines of action all intersect at a common point. The correct term for this is concurrent forces. Concurrent forces may not necessarily be in contact with the common point of intersection, but their lines of action do cross at a single point.

When dealing with a point acted upon by two forces in equilibrium, the forces have equal magnitudes but opposite directions. This is because forces are vectors, which means they have both magnitude and direction, and the vector sum of the individual forces must be zero for the object to be in equilibrium. Therefore, Essential Knowledge 3.B.1 applies, which states that the net force is the vector sum of the individual forces.
