Aha! A little bit of thought, some Google, and a practice problem have let me figure out that the moment at B due to both the reaction at B *and* the force at A must be considered. Thus, the moment due to F must be equal but opposite to the moment due to the reaction at B (i.e. M-sub-A minus...

Evidently the force in AC will have an X-component and a Y component, as will the reaction at C (the reaction at B will only have an X-component. I am largely concerned with identifying what these values might be, as a function of the moment, force, distance, angle etc. I am "tripped up" by the...

Right. If you have a Force parallel to the Y-axis though, it only has 1 component. Then we need to figure out what effect that Y-Force will have on the X-aligned member AB and the slanted AC. We can say that AC is at angle (theta) to AB for simplicity. Then I'm not sure how to proceed with...

More like you have a triangle that's completely suspended against a wall (no points on the ground), with B in the lower-right, C in the upper-right, and A aligned with B in the X-axis. Then the angle ABC is a right angle. Not like a traditional "Angle Bracket" like you would find at a hardware...

Homework Statement This is a general question about Statics. I was not able to find a specific question that includes this situation. I have a right triangle ABC with two (or three) members. Member AC is diagonal with a pin support (prevents translation) at C. Member AB is horizontal with...
