@@ElCrankoPunko No, they are not pinn connected, the two members have sliding surfaces on each other due to a pin that engages the two members together.
Why force fc is acting perpendicular to joint c? The member AC is a force member so the force should be acting perpendicular to the frame BCD right? I didn't understand why the force acts on that direction which doesn't make sense to me honestly
Good question! Force Fc is perpendicular to the slot! You always have a reaction force when there is a resistance to motion! There is no resistance parallel to the slot and the other component of force would be perpendicular to the slot.
The force acting on the rod is perpendicular to the direction of slot at AC, since the rod can move in that direction, the reaction force does not have any component along AC and the only component would be perpendicular to the rod AC. Does that make sense?
You are right. I mis-spoke in the video. Both 500 and Fc are creating counter clock wise moment, so their sign is the same and different than Dy which is creating clock wise motion.
Dr Sanei can you explain the significance of the smooth slot in member AC
The term "smooth" indicates that there is no friction (neglected) and the only force would be the normal force acting between the two members.
I wanted to ask is that the smooth slot in member AC is like pin connected to smooth rod ?
also wanted to ask where there will moment reaction in the slot or not
@@ElCrankoPunko No, they are not pinn connected, the two members have sliding surfaces on each other due to a pin that engages the two members together.
@@ElCrankoPunko No, there is no moment reaction as there is no resistant to rotation. You can think of it as sliding a box on a surface.

idk how the angle FC is found ??

I do not understand why 500lb is making a clockwise moment?

@@engineeringvision That makes more sense thanks!
