Use free body diagrams and the Method of Joints to calculate the force in each beam or member of a truss.
Solve for the reaction forces acting that the pin and roller supports which are holding up the truss.
Use a common sense approach to determine whether each beam within a truss is under tension or compression.
Trusses are a fundamental part of the study of static structures and static equilibrium. Truss Analysis comes up in most courses that deal with statics. This includes introductory physics courses such as high school physics, AP Physics 1, AP Physics C Mechanics. As well as introductory engineering courses such as PLTW Principles of Engineering (POE).
This problem also serves as the foundation for more advanced statics engineering courses that appear at a college level in fields such as civil engineering.

This was amazing, I find that many other videos just talk about tension and compression without any reference as to whether they are talking about forces acting on a member or forces that a member exerts to oppose external forces, which led me to be more confused than when I started. You've reaffirmed my initial intuition of what each force represented. Thank you

the forces ON the beam vs the forces BY the beam is always a point of confusion, largely because different instructors / texts handle it differently, sometimes without being expliccit about what they are doing.

Brilliant explanation on method of joints. I could never quite get this in my structures class but now I've got it, cheers.

Thank you for making the best video I've seen on this subject. Sharing with my students tomorrow. 🙂

It's all force/load equilibrium.

perfect video really the only video I could understand anything off of about the method of joints I just didn't understand how you used the Pythagorean theorem to find the force in beam BD

If you know any two sides of a right triangle you can solve for the 3rd using the pythagorean theorem.

Sorry, I don't get how you got 33.7 degrees. 2^m and 3^m equals 33.7 deg?

How did you get that F(ab)= 90.1N ? I’m getting AB= 66.1N

@SaleenJ 6 ай бұрын

What if AB is plastic and BD is steel?

that wont change the calculations, but it will affect which member is likely to fail first.

it is very hard to imagine in my mind how the wooden beam can actually stretch like a spring and having a tension force...

@dandelareye5233 Ай бұрын

The molecules that make up the wooden beam do not touch but are instead held by intermolecular forces of attraction. These intermolecular forces are the results of attractions between charges. The molecules of the wood are similar to two magnets that are attracted to each other. As you try to separate the magnets, there comes a point where there is a gap between the two magnets but they are still close enough to be strongly attracted to one another. This is how the wooden beam can "stretch". Although the "stretches" are molecular in nature.
