Hello, Enjoying the course, but I was wondering if maybe these were uploaded in the wrong order? Sometimes you refer to things (like a member, etc) without having prior explained. It also feels like forces and moments should be closer together and that theres a part where you discuss the cross product way later than the dot product? At times it just feels as if it's getting a bit confusing. Thanks.
I think that strictly speaking, at 4:45 in the larger blue picture there need to be forces on the base of the crane pointing sideways. Of course, for a typical crane, these forces would be zero, but it is not mathematically impossible to have some sort of horizontal strain in the base.
My doubt is how can i know ,how loads are transferred by using a freebody diagram of a chair or a table to explain how it works or rather how loads transfers

If I'm getting this right, the sign convention means that the force vectors that you paint into the picture actually act away from the drawn body.
