I can't understand why I can't get this problem right. It's irritating me, so any help would be greatly appreciated.(adsbygoogle = window.adsbygoogle || []).push({});

The Problem: The drawing shows a jet engine suspended beneath the wing of an airplane. The weight W of the engine is 9300 N and acts as shown in the drawing. The rotational axis in the drawing is perpendicular to the plane of the paper. With respect to this axis, find the magnitude of the torque due to the following force: the weight.

Drawing

I know how to find torque using Torque = Fl

Initially my equation consisted of:

Torque = 9300(2.50)cos 32 - But my answer was wrong. So I then thought perhaps I should being using gravity in there since W = mg. In using that my second equation consisted of:

Torque = 91140(2.50)cos 32 - But again my answer was wrong.

What am I missing?? This should not be that difficult that's why I'm getting frustrated that I can't figure out something simple, that I'm not just doing right.
