Can the sum of the torques on an object be zero?
Yes, for an object in static equilibrium , the sum of the (external) forces acting on the object must be zero and the sum of the (external) torques acting on the object must be zero.
What will happen to an object if the total torque acting on it is not zero?
Question: What will happen to an object if the total torque acting on it is not zero? Its moment of inertia will increase. It will rotate with constant angular acceleration.
When an object is in equilibrium what is zero acceleration?
A moving object is in equilibrium if it moves with a constant velocity; then its acceleration is zero. A zero acceleration is the fundamental characteristic of an object in equilibrium.
When an object is in equilibrium to sum of the forces must equal zero?
If the object is at equilibrium, then the net force acting upon the object should be 0 Newton. Thus, if all the forces are added together as vectors, then the resultant force (the vector sum) should be 0 Newton.
Can the sum of the torques on an object be zero while the net force on the object is non zero explain?
2 points Can an object be in equilibrium if it is in motion? Explain. Solution: Yes, the condition of equilibrium is the all of the net forces and all of the net torques is equal to zero.
What is the sum of the torques?
The sum of the torques is equal to the rotational mass (or moment of inertia, I) times the angular acceleration (denoted by the lower case Greek letter omega, ω). The 2nd law tells us that if the object or system is motionless, the angular acceleration is equal to zero.
Can the sum of the torques on body be zero while the total force on the body is nonzero explain?
According to Newton’s third law, the sum of all the internal torques is zero. For an object to be in mechanical equilibrium, the net external force and the net external torque acting on the object have to be zero. The total torque can be nonzero, even though Ftot = 0.
When you apply the torque equation to an object in equilibrium the axis about which torques are calculated?
When you apply the torque equation Στ = 0 to an object in equilibrium, the axis about which torques are calculated must be located at a pivot. must be located at the object’s center of gravity.
What happens to an object if it has no acceleration?
If there are no forces acting upon the object, then there is no acceleration. If there is no acceleration, then the object will move with a constant velocity. We know that the force is zero.
Is it possible for a spinning object to have a zero net force?
An object may be rotating, even rotating at a changing rate, but may be in translational equilibrium if the acceleration of the center of mass of the object is still zero. In the diagram shown above, the net force acting on the rod is zero and the acceleration of the center of mass also equals zero.
Can there be torque if net force is zero?
If an object is in motion at a constant speed and constant direction, and/or is rotating at a constant rate, then that means there is no linear or angular acceleration which implies that the net force and net torque are equal to zero–which implies equilibrium.
