The two conditions of equilibrium were applied to the rigid body, or meter stick, and various torques and lever arms were calculated. Unknown positions and masses were also calculated.

Equilibrium of a rigid body-conditions and physics A rigid body is said to be in mechanical equilibrium if both its linear momentum and angular momentum are not changing with time. In other words, the body is in mechanical equilibrium when it has neither linear acceleration nor angular acceleration.

What are the conditions of equilibrium of a rigid body?

Conditions of equilibrium of a rigid body acted upon by a system of concurrent forces in plane (here describe two conditions): (i) If an object is in equilibrium under the action of three forces, the resultant of two forces must be equal and opposite to the third force.

What are the two conditions for equilibrium?

Here are the two conditions for equilibrium and their respective equations. (1) The total or net force i.e. the vector sum of all the forces, on the rigid body is zero. (2) The total Torque i.e. the vector sum of the torques on the rigid body is zero.

When does a rigid body show translational equilibrium?

This implies that the body under the influence of external force neither has a linear acceleration nor an angular acceleration. We, therefore, can say that: If the total force on a rigid body is zero then the body shows translational equilibrium as the linear momentum remains unchanged despite the change in time:

What are the conditions for rotational equilibrium?

For rotational equilibrium, it is necessary that all the three components result in a zero. Moreover, as the translational equilibrium is a condition that depends on a particle’s behaviour, therefore, the vector sum of forces on all the particles must be a zero. Equilibrium in a rigid body may also be partial in nature.

Torques and Rotational Equilibrium of a Rigid Body Objective: • Apply the conditions for equilibrium of a rigid body to a meter stick pivoted on a knife edge. • Determine the center of gravity of the meter stick, mass of the meter stick, and mass of an unknown object by applying known torques.

What is torque and rotational equilibrium?

LAB 6: TORQUE AND ROTATIONAL EQUILIBRIUM This is a DIY lab. This lab is adapted from references 1 and 2. Objectives Forces acting on a body of finite size tend to both translate and rotate the body. If the body is to be in equilibrium, it must be in equilibrium both with respect to translation and to rotation.

What are the conditions for rotational equilibrium?

Rotational equilibrium states that the net torque acting on the object is zero as well as it has zero angular acceleration. Where ∑ →T ∑ T → shows the vector sum of the torque acting on the object. In scalar form, the conditions for rotational equilibrium are given by,

How does torque affect rotation?

Torque and Rotational Equilibrium Introduction If a force acts on a rigid body that is pivoted about some axis, the body will tend to rotate provided that the line of action of the force does pass through the pivot. The tendency of a force  to cause a body to rotate about some axis is measured by a quantity called torque, τ .

How is rotational equilibrium achieved in this experiment?

Rotational equilibrium will be achieved if the magnitudes of the positive and negative torques are equal. In this experiment, a metre-stick is used as an approximation of a rigid body. External forces are applied by suspending masses from it.

What is equilibrium of the body?

Equilibrium of the Body: Equilibrium in physics is the system’s condition when neither its state of motion nor its internal energy changes with time. When a simple mechanical body does not experience linear acceleration and angular acceleration, it is known to be in equilibrium.

What test tells us whether or not a moving object is equilibrium?

What test tells us whether or not a moving object is an equilibrium? If the moving body doesn`t change its velocity, it is in equilibrium. If the body changes its velocity, it is not in equilibrium. Consider the video demonstration that you just watched.

What is meant by stable equilibrium?

Stable equilibrium:- A body is said to be in stable equilibrium whenever we displace the body by a small distance; the state produces forces that tend to oppose the displacement and returns the body to its state of equilibrium. In this equilibrium, the body will be very stable.

Various masses were placed on the meter stick at certain distances in order to obtain translational and rotational equilibrium. The lab consisted of five parts, in which multiple forces were added on the meter stick as the lab continued.

What is translational equilibrium?

(Rotational equilibrium – Principle of moments) The vector sum of forces on object is zero. (Translational equilibrium) Consider the diagram above, whereby a plank is supported by a pivot. Two forces, 120 N and F are acting on the plank. Given that the plank is perfectly balanced (has rotational equilibrium), find F.

What are the conditions for rotational equilibrium?

Rotational equilibrium states that the net torque acting on the object is zero as well as it has zero angular acceleration. Where ∑ →T ∑ T → shows the vector sum of the torque acting on the object. In scalar form, the conditions for rotational equilibrium are given by,

What is the difference between translational and rotational motion?

Translational motion happens when a body moves from one point to another, and rotational motion occurs when a rigid body revolves around an axis. Both these types of motion have states of equilibrium associated with them.

What is the relationship between motion and equilibrium?

Equilibrium is the state of being balanced physically, and it is an important factor for being in motion. Explore the relationship between motion and equilibrium, focusing on the two types: translational and rotational. Updated: 10/28/2021
