I am working on the problem... a 670 Newton swimmer oriented horizontally in fresh water has a body volume of .07 m3 and a center of volume located at 3 cm superior to the center of gravity. How much torque does the swimmers weight generate?? I am puzzled by the body volume being included in the problem. I want to just take 670N x .03m and say that is the torque. However I feel like that is missing something. I know the equation for torque = force x radius (perpendicular) . Any suggestions??
