Yeah, from the diagram given, it looks as though the force is applied at O, so there is no net torque.andrewchang said:if the force is going through O, and you set the axis of rotation at O, then there is no net torque. (the radius is zero)
Net torque is the overall measure of the rotational force acting on an object. It takes into account the magnitude and direction of all individual torques acting on the object.
Net torque is calculated by multiplying the magnitude of each individual torque by its distance from the axis of rotation and then summing all of these values together.
An axis through O refers to the point at which the object is rotating. It is often referred to as the axis of rotation or the point of rotation.
Finding net torque is important because it allows us to understand the rotational forces acting on an object and determine its overall rotational motion. It is also necessary for solving problems involving rotational equilibrium.
To find the net torque about an axis through O, we need to identify all individual torques acting on the object and their distances from the axis. Then, we can use the formula net torque = Στ = ∑F x r to calculate the overall net torque.
