A 49-N force is applied perpendicular to the portion BC of the bent bar. Determine the moment of P about point B and about point A.
The image shows a bar that is straight from point A to B but then bends at a 42 degree angle to the left from point B to point C. The distance from A to B and B to C is 2.0m.
I determined the moment at point B (before the bend) as the simple calculation 2*49 and got 98.
My question is about the moment about point A. What steps should I take to figure this out?
