What is the relationship between rolled distance and time taken?
If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.
Is it possible that if equilibrium is established it is still equilibrium even if the ring move horizontally away from the force table?
yes. Equilibrium can either be static i.e no movement or dynamic i.e movement is allowed. The main determining factor for equilibrium is that all forces acting at a point or points add up to zero.
How we explain varignon's theorem and prove them?
The Principle of Moments, also known as Varignon's Theorem, states that the moment of any force is equal to the algebraic sum of the moments of the components of that force. It is a very important principle that is often used in conjunction with the Principle of Transmissibility in order to solve systems of forces that are acting upon and/or within a structure.Type your answer here...
How does acting have to do with math?
Well to be an actor you have to be good with acting singing and dancing so math does not have anything to with acting
If the velocity of a particle is nonzero can the particle's acceleration be zero?
yes. If the forces acting on the a moving particle are in equilibrium, (e.g. when a spherical object reaches terminal velocity (neglecting increased air resistance as it gets closer to the ground)) then the particle will be moving at a velocity, that is not 0, yet the velocity will remain constant, and the body will not accelerate or decelerate in any direction, and thus the acceleration is 0.
What theorem states that if three forces acting at a point -they are in equilibrium-then each force is proportional to the sine of the angle between the other two?
It is Lami`s theorem.
What are the conditions of lami's theorem?
Lami's theorem states that if three forces are in static equilibrium, then the magnitude of each force is proportional to the sine of the angle between the other two forces. Since the forces are in static equilibrium, they sum to zero. This means that if the force vectors are put end-to-end, they form a triangle. The "law of sines" applies to any triangle, and states that the length of each side is proportional to the sine of the opposite angle. Interpreting the sides as force vectors, we get a statement of Lami's theorem.
What is the rule for the force of gravity?
The force of gravity is directly proportional to the product of the mass of the two objects ,between whom the force is acting , and inversely proportional to square of distance between them.
At what angle is the resultant force acting?
it is acting opposite the the equilibrium.
Can a body in equilibrium if it is in motion?
It can be in equilibrium if in constant motion (constant velocity) as no forces are acting on it (no acceleration)
When is an object in equilibrium?
When the forces acting on the object are stable
How a body is said to be in equilibrium?
A body is mechanical equilibrium if the sum of the net forces acting upon it is zero.
What is the net torque acting on an object in rotational equilibrium?
There is none
How does gravity determine the force acting on an object?
It doesn't. All gravity does is create a pair of forces, in opposite directions, between the center of the object and the center of the Earth, that's proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Gravity has no effect on the magnitude, number, or direction of other forces that may be acting on the same object.

What is a state in which all forces acting on an object are in balance?
Equilibrium is a state in which all forces acting on an object are in balance.
Why a body cannot be in equilibrium due to single acting on it?
A body is in equilibrium when the force on it is zero, thus if a single force is on the body, the force must be zero or the body will not be equilibrium.
