Satellite technology is a fascinating field that makes use of some very clever engineering to overcome the challenges of designing for the space environment. This video explores the seven subsystems - the structure, the on-board computer, the electrical power system, the attitude determination and control system, the propulsion system, the communications system and the thermal control system - that make up a typical satellite bus.

    Did this guy just casually and fluently explain the 2 Schwedler equations in less than few minutes INCLUDING THE PICTURE AND HOW IT CAME TO BE? 🙃 I was trying to understand this, all sweaty before the exam, took me like an 30 minutes to do so, when I just could watch this video X).... Well, at least made it at the end, and even with grade 2, which out of like 50 people, from which 1/5 actually made it is quite good I think 😅😂. Will definitely watch this channel more, since I saw all the possible things scuh as thermodynamics that will come next year 💀👍

    A couple 'funny' animations: 0:05 The ends move up and down, a lot, even tho the load is only between the supports. The straight ends should have no curvature outside of the supports. 4:36 Wow, that copper stretches a LOT, like 300%, and then goes right back to its original shape. That doesn't work for many reasons, not the least of which is simple conservation of mass, the rod's diameter never changes while expanding in volume 3 times.

    06:32 You mention turballent velocity profile around the object is less stiper (Hence less shear stress which proportional to the gradient of the velocity) However you infere that laminar flow is less drag, is that should be the opposite ? of something in the explanation is missing?
