How does torque relate to equilibrium?
A torque is a vector quantity which means that it has both a magnitude (size) and a direction associated with it. If the size and direction of the torques acting on an object are exactly balanced, then there is no net torque acting on the object and the object is said to be in equilibrium.
What is the relation between rotational equilibrium and torque?
Rotational Equilibrium is analogous to translational equilibrium, where the sum of the forces are equal to zero. In rotational equilibrium, the sum of the torques is equal to zero. In other words, there is no net torque on the object.
What is the relationship between net torque and static equilibrium?
If the object is in static equilibrium, then it is experiencing zero net force, which means that no matter what reference point we choose, the net torque will be the same.
How do you find torque in physics?
Measure the distance, r , between the pivot point and the point the force is applied. Determine the angle θ between the direction of the applied force and the vector between the point the force is applied to the pivot point. Multiply r by F and sin θ and you will get the torque.
Is torque rotational equilibrium?
The concept of rotational equilibrium is particularly useful in problems involving multiple torques acting on a rotatable object. In this case it is the net torque which is important. If the net torque on a rotatable object is zero then it will be in rotational equilibrium and not able to acquire angular acceleration.
What is equilibrium physics?
equilibrium, in physics, the condition of a system when neither its state of motion nor its internal energy state tends to change with time.
What does torque depend on?
The magnitude of torque of a rigid body depends on three quantities: the force applied, the lever arm vector connecting the point about which the torque is being measured to the point of force application, and the angle between the force and lever arm vectors.
What are the 3 factors that determine torque?
Examples: Page 5 Torque is Determined by Three Factors: The magnitude of the applied force. The direction of the applied force. The location of the applied force.
Why does torque increase with distance?
Torque increases as distance away from the fulcrum a perpendicular force is applied. It also increased when the force itself increases. So perpendicular force and distance directly relate to torque.
What causes torque to increase?
Torque can be increased in two ways: 1) by increasing the moment arm or 2) increasing the perpendicular force applied to the moment arm. The opposite is true for decreasing torque. If an object is at rest the torques on the object are balanced (they cancel out) and sum of those torques is zero.
What are the factors affecting torque?
How can we increase or decrease torque?
Hence, in order to decrease this turning effect (or moment of torque), one can either reduce the force applied or decrease the distance between the line of action and axis of rotation and viceversa.
