Why should the central ring be balanced in polygon law of forces?
The central ring should be balanced in the polygon law of forces to ensure that the net force acting on it is zero. This balance is crucial for maintaining equilibrium, meaning that the ring will not experience any unbalanced forces that could cause it to move or rotate. When the forces are balanced, each vector in the polygon can be represented as a side, forming a closed shape that visually illustrates the equilibrium of forces acting on the ring. This concept is essential in various applications, such as engineering and physics, to ensure stability and proper functioning.
How does a suspended magnet come to rest?
A suspended magnet comes to rest when the magnetic forces acting on it are balanced by other forces, such as gravitational and frictional forces. When the magnet is freely suspended, it will rotate until its magnetic field aligns with the Earth's magnetic field, reaching a position of equilibrium. Additionally, any oscillations or movements will gradually diminish due to air resistance and internal friction, leading the magnet to settle in its most stable orientation.
What are anticlockwise and clockwise equilibrium?
Anticlockwise equilibrium refers to a state where the net torque acting on an object causes it to rotate counterclockwise, while clockwise equilibrium refers to a state where the net torque causes the object to rotate clockwise. In both cases, the object is in rotational equilibrium because the torques are balanced and there is no angular acceleration.
Can a couple be said to be dynamic equilibrium if yes does its resultant moment not contradict the definition of equilibrium?
No, a couple is not in equilibrium, unless there is an equal and opposite force acting against each member of the couple.Be sure to remember that something can still be moving even if it is in equilibrium. It just means it's not accelerating.A2 People often forget that there is a difference between a hypothetical point sized object and a typical sized object when applying the condition for equilibrium. If the forces on an object are equal and opposite it is only the centre of mass that is required to be at rest (or moving at constant velocity). So for a point sized object that means the entire object must be at rest. But for a typical sized object only the centre of mass is required to be at rest. If the applied forces are off centre (as with a couple) it is still possible for the object to rotate about its centre of mass. This is dynamic equilibrium. If one also applies the second condition for equilibrium then you can have static equilibrium (no motion of centre of mass and no rotation) if the system is initially at rest. The second condition for static equilibrium is that there be no net torque on the object. That is the off centre forces tending to rotate the object(say clockwise) must be balanced by other off centre forces which tend to rotate the object counter clockwise.

What happens to an object if the torques acting are not balanced?
The object will undergo rotational acceleration: it will either rotate faster or slower than previously.
When two forces are acting in the same direction the net force is?
Balanced force means two forces are acting on opposite sides of body and that body doesn't change its position.Nothing. Zero newtons. Zilch :L
What happens when moments are unbalanced or balanced?
When moments are unbalanced, it means that there is a net torque acting on an object, causing it to rotate. This can result in rotational motion or change in angular velocity. When moments are balanced, the total torque acting on the object is zero, resulting in either no rotation or constant angular velocity.
Do metors rotate?
Yes, meteors can rotate as they travel through Earth's atmosphere due to the forces acting on them during their descent. This rotation can be caused by factors such as air resistance and the irregular shape of the meteor.
How do you know that the forces on a windmill are unbalanced?
When the forces on a windmill are unbalanced, the blades may slow down or speed up, or they may change direction. When the blades are rotating at a constant velocity (speed and direction), then the forces are balanced.
What is a couple acting on a body?
A couple acting on a body is a pair of equal and opposite forces that do not have a resultant force but do produce a turning effect or moment on the body. This can cause the body to rotate around its center of mass.
When the forces on an object produce a net force of zero is called what?
That's called a 'balanced' group of forces. Their effect on the object's motion is the same as the effect of zero force ... the object may rotate, but it won't accelerate.
What forces act on a pulley?
The forces acting on a pulley are tension forces exerted by the ropes or cables pulling on it. These tension forces cause the pulley to rotate and transfer motion and forces between different parts of a system. Frictional forces may also act on the pulley, depending on the surface it is in contact with.
How does a suspended magnet come to rest?

What forces act on a windmill?
The main forces acting on a windmill are the wind, which provides the driving force to rotate the blades, and gravity, which acts to support the structure and weight of the windmill. Additionally, there may be internal forces within the windmill components such as tension and compression forces in the blades and tower.
When you rotate tires should they be spin balanced?
