Is the rod is equilibrium?

For an object to remain in equilibrium, two conditions must be satisfied – both the net force and the net torque must be equal to zero. An example of an object in equilibrium is a rod that is free to rotate about a hinge at one end.

What are the 4 types of equilibrium?

Types of Equilibrium.

• Stable Equilibrium.
• Unstable Equilibrium.
• Neutral Equilibrium.

Why the rod is not in equilibrium?

In the diagram shown, a force is applied at the center of the rod. Because of this force, the rod translates and the center of mass of rod accelerates, but the rod does not rotate and remains in rotational equilibrium. In this case, the torque about the center of mass is zero.

How do you find the torque of a rod?

There are three equivalent ways to determine this torque, as shown in the diagram below. Method 1 – In method one, simply measure r from the hinge along the rod to where the force is applied, multiply by the force, and then multiply by the sine of the angle between the rod (the line you measure r along) and the force.

What is neutral equilibrium?

A body is said to be in neutral equilibrium if on being slightly displaced it remains in its new position; e.g., a ball placed on a horizontal surface or a cone supported on its side on a horizontal surface.

What are the examples of neutral equilibrium?

5 examples of neutral equilibrium

• Ball moving on the ground.
• Motion of sphere.
• A roller.
• A pencil lying horizontally.
• An egg lying horizontally on a flat surface.

What is mean by stable unstable and neutral equilibrium for which equilibrium is the potential energy of the system is minimum?

If the force is restoring i,e direction is towards the equilibrium position then it is a stable equilibrium. if the force is away i,e direction is away from the equilibrium position then it is an unstable equilibrium. If no force acting then neutral equilibrium. Equilibrium And Potential energy.

Which is not a type of equilibrium?

Therefore, negative equilibrium is not a type of equilibrium.

What is not the condition for the equilibrium in calculations involved in the determination of the Centre of mass?

6. What is not the condition for the equilibrium in calculations involved in the determination of the centre of mass? Explanation: For the equilibrium in the three dimensional system of axis we have all the conditions true as, ∑Fx=0, ∑Fy=0 and ∑Fz=0. Also we have the summation of the forces equal to zero.

What is the net torque of the rod in equilibrium?

To keep the rod in equilibrium, the net torque should be zero. As a result, writing torque about the hinge, torque of gravitational force and force F are in opposite directions.

What is the net force acting on the rod?

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. About center of mass both forces produce the torque in the same sense that is anticlockwise. Thus, the net torque is non-zero and the body is only in translation equilibrium.

Can an object Translate with variable speed and still be in equilibrium?

Similarly, an object may be translating with variable speed and still be in rotatory equilibrium. In the diagram shown, a force is applied at the center of the rod. Because of this force, the rod translates and the center of mass of rod accelerates, but the rod does not rotate and remains in rotational equilibrium.

When a body is said to be in equilibrium?

A body is said to be in equilibrium if it continues its state of rest or its state of uniform motion. Equilibrium can be categorized in two ways: 1) Static equilibrium: If a body is at rest and remains at rest, then the equilibrium is said to be static equilibrium.
