A square, 0.40 m on a side, is mounted so that it can rotate about an axis that passes through the center of the square. The axis is perpendicular to the plane of the square. A force of 15 N lies in this plane and is applied to the square. What is the magnitude of the maximum torque that such a force could produce?
PHYS 2010- Chapter 4 Notes What Is Force Definition: A force is something that is changes or tends to the state of rest or motion of an object. Force is not a thing on its own, its arises from interactions between objects. A force is avector. Described by a magnitude and a direction All vector rules apply. SI Unit of force: Newton, symbol N. Forces – Agent & Object A force is a push or a pull. Other examples: lifting, pressing, twisting, stretching…etc Force is a vector, it has magnitude and direction. Hence, we can draw vector diagrams for force. Combining Forces Net Force: Combination of all forces acting on 1 object at one time. Net force may be balanced or unbalanced. When several forces are exerted on an object, they combine to form a net force equal to the vect
