Since the arrows are pointing down for Wa, Wb, and Wc that'll allow those forces to rotate counter-clockwise about the y-axis (which is positive). And since F is pointing up the force will rotate clockwise about the y-axis, therefore making it negative. You have to kinda visualize how the force rotates about an axis given the way the arrow is pointed. Hope this helps.
Take my very poor explaination with a huge grain of salt, but this is what I think happened. D + E = 45.26 kip D = E (D + E) = 2D = 2E D = E = 45.26 / 2 = 22.63 Don't know if this made sense, and I hope it's not wrong.
Since we know that D=E, we can say that 2D or 2E is the same as D+E. So we replace D+E with either 2D or 2E. We already know F and now we can solve the equation since there’s only one unknown. So you can write D+E=45.26 as 2D = 45.26 or 2E = 45.26 and solve for either variable that way. Since we know that D=E, we’ll get answers for both just by solving for one of them
Nice explanation sir
Very good and funny videos bring a great sense of entertainment!
can some plz help with me understanding the direction of forces. for example how he got clockwise sum of M of y

quick question.
why did it go from
D=E=45.26 kip
to
2D=2E= 45.26 kip
Where did the 2 come from?
Thank you
Take my very poor explaination with a huge grain of salt, but this is what I think happened.
D + E = 45.26 kip
D = E
(D + E) = 2D = 2E
D = E = 45.26 / 2 = 22.63

First of all there would never be wheels underneath the wing of the airplane
yes you will. Every plane has wheels under the wing.
@@DTT420 no numbnuts every plane has wheels under the fuselage
@@samveillon1915 Some, but only either the humongous or certain small ones, are on the wing or the engines, but it's not really enough to notice
