Question

Which two-dimensional force system has all the forces intersecting at one point?

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

Answer 1

Concurrent forces is the two-dimensional force system in which all the forces intersect at one point.

Step-by-step explanation:

The correct answer is a) Concurrent forces. Concurrent forces constitute a two-dimensional force system where multiple forces converge at a single point, known as the point of concurrency. Despite varying directions and magnitudes, each force's line of action intersects at this common point. This characteristic distinguishes concurrent forces from coplanar forces, which share the same plane but lack a single point of intersection. The point of concurrency simplifies force analysis and is a fundamental concept in mechanics, enabling the determination of resultant forces and their effects on objects subjected to multiple force vectors.
