Moisture content should be the difference of the weight of the object wet (10 oz.) and the weight of the object when it was dry(8 oz.) So, 10 oz. - 8 oz. =moisture content, or 2 oz.
The mechanical advantage of a machine is the ratio of the force that you need to input to how much is outputted. 200:1000=1:5, meaning that the mechanical advantage is 5. Hope this helps!
