Common mistake
Misunderstanding Moment Calculation
Students often confuse the moment of a force with just the force applied, neglecting the importance of the perpendicular distance from the pivot.
To fix this, remember that the moment is calculated using the formula: moment = force x perpendicular distance. Always ensure you include both the force and the distance in your calculations.
