## Homework Statement

The weight of the printer is 86 lb with center of gravity at point G. Determine the moment MOof this weight about point O on the horizontal table top. Find the magnitude of MO.

## Homework Equations

## The Attempt at a Solution

My initial impression was to find the moments about the x, y and z axes and that these would give me their i, j and k components respectively

M

_{x}= (86 lb)(52")

= 4472 lb-ft

M

_{y}= (86lb)(22")

= 1892 lb-ft

But I've compared these values to an identical question, with altered numbers, in my textbook and my values are much too large to be be the i and j components respectively (there is no k component because the force is parallel to the z axis). So what am I missing?
