Looking for practice problems with solutions? I also created a whole set of fully solved statics problems with step-by-step hand calculations:

Looking for software? I highly recommend checking out SkyCiv. They make a full suite of online structural analysis software and tools that are useful for both students and professionals, including calculators for beams, trusses, frames, moment of inertia and more. It’s great for checking your work:

in my first year of mechanical engineering, I got my first statics exam soon. Well, I love youtube and I love you for making these videos. You are helping a lot of us noobies!

[sarahguynup]

Thank you for the explanations. It helped me a lot trying to complete my Statics class project.

was able to do my entire assignment watching your videos, thanks a lot man !

For those from the previous video the bottom left diagram is missing two ZFM (as stated in his description). It is the members that connect from the to the bottom of the truss 1/3 from the right.

nice videos bro. so much better than my lecturer

Saved one more engineering student here lol. I don't know why now i believe in myself to get a good grade in the exam although I could not understand what is going on with my mechanics throughout the whole semester

Thank you bro . You have done a good explanation !

on the truss on the left, what was the justification for keeping the members of the acute triangle? the right side of the triangle is the third member of collinear members, why would it not go to zero?

Hi, brilliant video, I just want to ask about 4:42, what observation can be made about zero force members if that load were just to be one of the two components - i.e either just in line with the collinear members or just in line with the perp. member. Additionality what observation could be made for the mentioned scenarios if the member were not perfectly perpendicular to the collinear members?

thank you
i will tell my result, of my test, which is tomorrow!!

Do you think ZFM is the first principle to learn in Analysis of Structures in order to solve with ease or are there other important ones prior to this? Btw, nice vid!

In the first diagram why didn’t you cancel out the 2nd member from right. It doesn’t have any internal forces .

[borislavvuletici]

Excellent presentation. Picture in the bottom left position has 4 joints in the bottom line. The 3rd joint from the left is connected to the top joint. Shouldnt this connection be ZFM?

One doubt right second vertical member also make system in unbalanced, then should be removed

In the bottom left picture, how come the third from the left internal beam is not zero force?
