1. The problem statement, all variables and given/known data The handle of the hammer is subjected to the force of F = 20. Determine the moment of this force about the point A. http://s3.amazonaws.com/answer-board-image/3214a2db-1a55-4648-b582-5f36f0f34451.jpeg 2. Relevant equations Principle of moments: Mo = FxY - FyX 3. The attempt at a solution I have broken the force into x and y forces and using the Principle of moments: Mo = FxY - FyX I have gotten 20cos30(18)-20sin30(5) however in the solution manual the answer is -20cos30(18)-20sin30(5). How do I know where to put what signs in these kind of equations. I know that positive is CCW and negative is CW but when broken into components how do you know what signs to use?!
