The hand below pulls on the handle bar with a force F. The point of application of the force is at A. The magnitude of the force is 110 N, and its direction is described by the unit vector u = (2/3i – 2/3j – 1/3k).

1. Determine the moment created by F at a moment center at O

2. Find the magnitude of the moment

3. Find the direction cosines associated with the moment

[ Hint : the components of F is found by multiplying the magnitude by the unit vector]

I can't upload the picture but the dimensions from the end of the handle (O)/point of origin, to the of the hand on the handle, are as follow:

250mm in the positive x-direction

200mm in the positive y-direction

150mm in the positive z-direction
