I see. So basically you use the ΣFY and ΣFX equations, but substitute the Y and X force components for B and C with their hypotenuse equations, and skip using trigonometry since we know all 3 sides of the triangle, and the forces through the objects act like pin-jointed trusses (forces only...
Hi all,
ProgrammingPE:
I've managed to solve this problem now. FB=4,66kN and FC=2,95kN by using the X and Y net force equations:
Net force in Y-direction gives Fby+Fcy= 6,25kN. (Eq. I)
Net force in X-direction gives Fbx = Fcx (Eq. II)
And using some basic trigonometry: Substitue both terms in...
Hi all!
Lots of great advice here. Yes, the last line in my post was wrong, and is now corrected.
WARose: How do you combine them whem solving simultaneous? I've written what I found with net sum X and Y directions. Did you use trigonometry to combine the equations into one another...
Hi all,
I'm trying to refresh my knowledge from my BSc mechanical engineering degree 4 years ago and this specific structural frame problem has me stuck. There must be some basic line of thinking I've forgot.
Task: Find forces in A, B and C.
I start by making a free body diagram, and split B...
