Non-Concurrent Coplanar Forces Finding the Equilibrant for a 4 Force System, Engineering Mechanics

Описание: Welcome to Video 4 in the Engineering Mechanics / Engineering Science series!
In this tutorial, we move beyond concurrent forces and explore a non-concurrent coplanar force system. You are given the magnitude and direction of four separate forces that do not act at the same point, and your task is to determine the force required to establish equilibrium.

This lesson shows you step-by-step how to analyze and solve a 4-force non-concurrent system, including resolving forces, calculating components, determining the resultant, and finally identifying the equilibrant force needed to balance the system.

Perfect for students preparing for CXC, CAPE, Engineering Science, Applied Science, Technical Drawing, and early university-level Mechanics courses.

🔹 In This Video You’ll Learn
