Finding the intersection of a plane

[clickcaptain]

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!

Hi clickcaptain!

I can't quite visualise this …

doesn't the moment go along the pole, to where the pole meets the y-z plane?

If I'm wrong, perhaps you'd better give us more details.
