Not familiar with cofferdams but a friction force is just the normal force X the coefficient of friction. Sounds like in your case you would start with the 180tons. Multiply that by the coefficient of friction between the rubber and the steel. Then make sure to analyse the vector quantites of the 20 ton force. If this 20ton force is not perpindicular to the normal (180ton) force then it will likely be adding to or subtracting from the friction force depending on the vector quantities. Robert *edit Maybe I didnt say that right... The friction force is the sum of the forces normal to the contact surface multiplied by the coefficient of friction between the contact surfaces.... There we go=) Modified by rfox71 at Mon, Apr 10, 2006, 12:32:25
