Moments & couples 2D (for now) (cant move on :( ) Hey guys and girls, im new to this forum but been looking at it for a while, its a great read and always a challenge here or there, but for now i was hoping to get a little help :) 1. The problem statement, all variables and given/known data The direction of the two thrust vectors of an experimental aircraft can be independently changed from the conventional forward direction within limits. For the thrust configuration shown, determine the equivalent forces-couple system at point O. then replace this force-couple system by a single force and specify the point on the x-axis through which the line of action of this resultant passes. These results are vital to assessing the design performance. 2. Relevant equations http://188.8.131.52/dl/1364f79aea6cc95c449481aa34b672e5/46de37d0/image/4903phy.JPG any help would be really really helpful cheers!!
