Below in Figure 1, we have a frame supported at point B and C, and a force applied at A. The applied force, F A, has a magnitude of 2200 N. (a) Write F A in vector notation. (b) Let point B be the moment center. What is the resultant moment at point B due to F A? (MA@B =?) Calculate this using the cross-product. (e) Let point C be the moment center. What is the resultant moment at point C due to F A? (MAM =?) Calculate this using a method other than the cross-product.
