Force times perpendicular distance is the moment about a fulcrum. My last post pointed that out and that you need to calculate that distance. How can it be Unknown? It is defined all over the place and in your textbook(?). Have you looked anywhere else than PF? Keep looking until you find something that makes sense to you.JoeyCentral said:So the whole idea of calculating torque is still unknown to me.
Torque angle is the angle between the force vector and the lever arm in a free-body diagram. It is calculated by taking the inverse tangent of the force vector divided by the lever arm length.
Calculating the torque angle allows us to determine the direction and magnitude of the torque, which is a crucial concept in understanding rotational motion and designing mechanical systems.
Positive torque angle indicates a counterclockwise rotation, while negative torque angle indicates a clockwise rotation. This is based on the convention that counterclockwise rotation is considered positive in physics and engineering.
Yes, the torque angle can be greater than 90 degrees. This indicates that the force and lever arm are acting in opposite directions, resulting in a negative torque.
The magnitude of the force and lever arm both affect the torque angle. A larger force or longer lever arm will result in a larger torque angle, while a smaller force or shorter lever arm will result in a smaller torque angle.
