Solving a truss with the Method of Joints | Statics (example 1)

Описание: In this video, we solve a complete truss problem using the method of joints, explained step by step.
We begin by calculating the support reactions using the three equilibrium statements: the sum of all forces in the x-direction equals zero, the sum of all forces in the y-direction equals zero, and the sum of all moments equals zero.
Then we move joint by joint to find member forces (tension or compression), with clear sign conventions and quick checks.

What you’ll learn

How to set up support reactions (pinned and roller supports)

Applying equilibrium: the sum of all forces in the x-direction equals zero, the sum of all forces in the y-direction equals zero, the sum of all moments equals zero

Choosing the right joint to start (two unknowns rule)

Resolving forces at 45° (cosine = sine)
