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 mechanical equilibrium?
Mechanical equilibrium is: - the state of rest or balance due to equal action of two opposite forces. - the equal balance of any powers
Can an object be in equilibrium when only one force acts on it?
Mechanical Equilibrium is the state in which 2 or More forces act on an object , and cancel each other out. There has to be an even number of forces for them to cancel each other out. So no, a single force will not achieve mechanical equilibrium.
What does it mean to say something is in mechanical equilibrium?
It means there are no unbalanced forces, or the net force is zero. That means if a t rest it will stay at rest, or if in motion it will stay in motion with no acceleration.It means that there is no net force acting on the object(s). A body moving at constant velocity is in mechanical equilibrium. A body that is not moving is in static equilibrium.
How to make a system of forces in equilibrium just by changing the angles of forces?
By the changing the angles of forces, the system of the forces will be in equilibrium.
When sum of forces acting on an object equals zero what is it called?
-- The object can be called anything you want. -- The group of all forces acting on the object is called a balanced group of forces. -- The mechanical condition of the object is called equilibrium.
Can an object be in equilibrium if only one force acts upon it?
if only a single nonzero force acts on an object, its motion will change and will not be in mechanical equilibrium. There would have to be other forces to result in a zero net force for equilibrium.
Explain the Principle of Equilibrium and Free Body Diagram?
System is in the equilibrium if all the forces (external and reactional - internal) are in the equilibrium - resulting force is zero vector. Free body diagram is drawn for each body of the mechanical system. The body is disconnected from the system and contacts (sometimes called joints) are replaced by reactional forces. Then for each body equations of equilibrium can be written based on the principle of equilibrium.
What are the two forces that are in equilibrium in a star?
Hydrostatic and Equilibrium
Does a object in mechanical equilibrium have zero acceleration?
By the definition of mechanical equilibrium, Yes. Because the sum of forces is equal to zero, it can be seen from the equation F=ma that the total acceleration on the object must be zero in order for the equation to hold. The mass is only a constant in this equation in this situation, and remains unchanged.
What are the two types of mechanical advantage?
Those dependent on the vector resolution of forces (inclined plane, wedge, screw) and those in which there is an equilibrium of torques (lever, pulley, wheel).
What are the forces in equilibrium?
action and reaction
