Here is the problem: Replace the two forces afting on the pole by a wrench. Write a moment M associated with a wrench as a vector and specify the coordinates of the point P in the y-z plane through which the line of action of wrench passes. I already figured the moment to be ("T" and "a" are both scalar) M = Ta(4i - 3j) How would I go about finding the intersection of the plane? My train of thought is leading me towards the idea that I need to set x=0 but I'm not sure... thanks for the help in advance!!
