The animations helped me understand much better

Thanks to this channel, you really taught it with engineering aspects rather theoretical book explanation

[@tec-science]

Thank you for your appreciation

Amazing video Bro!

[@sprite522]

Great video !
what software did you use to make the animation of the belt pulley and the motor?

[@tec-science]

I use Blender for the animations

[@ymonga122]

could you please make video on Statical methods or method which are helpfull in getting 50% Probability curve out of Wöhler diagram
