HELP! Question on forces (Mechanical eng. problem!)
Tue, 16 August 2005 14:37
I'm having trouble drawing FBD's of reactions at pins that connects to a wall and a member,
how do you go on about selecting whhich direction the force is actually going?
here's an example
Sometimes I get confused when I look at one example in the text book and A_x and A_y are both point at the pin, and sometimes A_x and A_y are not (pointing in another direction)
Is there some sort of secret?
I believe member BC is a two force member... wish I didn't draw that
