Torques equilibrium‚ and center of gravity Introduction Torque is a quantitative measure of the tendency of a force to cause or change the rotational motion of a rigid body. A torque is the result of force acting at a distance from an axis of rotation. An essential thing to keep in mind is that the magnitude of the torque is equal to the product of the forces perpendicular distance and magnitude. Theory The magnitude of the torque (t) is found from the product of the force F and

Center of Gravity The point in a body or system of bodies at which the whole mass may be considered as concentrated. When an object’s weight is distributed uniformly‚ the center of gravity lies at its geometrical center. For irregular shaped objects‚ the center of gravity is near to the concentration of its mass. Equation: Where: X= center of gravity xi= distance of the objects from fulcrum or arbitrary axis mi= mass of the object Sample Problems 1.) Suppose your lab partner has

1)Scoliosis posture: the centre of gravity has shifted to either the left or the right depending on which side has the main curve on the spine. This will typically give the appearance of a wonky sideways walk. 2)Military posture: most people believe it is a perfect posture‚ but it is not ideal for these reasons. The centre of gravity has shifted slightly pushing the pelvis anteriorly and up‚ drawing the shoulders back‚ which draws the scapula back medially pushing the chest out and up‚ this causes

earth; gravity. Whenever I think of gravity‚ the same questions never fail to come to mind. What exactly is gravity? Could human life possible go on without gravity? How exactly does gravity work in terms of numbers and formulas? How was gravity truly discovered and defined‚ and by whom? Gravity is universal‚ and it not affects earth and its inhabitants‚ but also the entire nebulous of stars and planets. Gravity is the force that pulls all things toward the center of the earth. Gravity holds your

Gravity is the force that keeps objects close to the earth Not only does gravity keep objects close to the earth it also keeps the solar system revolving the sun Gravity was discovered by Isaac Newton Acceleration of objects that is due to gravity on Earth is 9.8 m/s Also‚ according to Mr. Newton’s First Law‚ once the egg was moving‚ it didn’t want to stop. The container of water interrupted the egg’s fall‚ providing a safe place for the egg to stop moving so you could recover it unbroken

The Centre of Gravity & its relationship to the Application of Sports Massage Introduction Every object has a centre of gravity‚ which‚ when combined with other factors such as the line of gravity‚ enables an object to balance. If a person or object moves or changes shape‚ the centre of gravity will also move. This is important to remember when discussing sports massage as the therapist is constantly moving‚ making them vulnerable to being unbalanced or unstable. So to be able to conduct a safe

The experiment consists of four activities. The Equilibrant Forces‚ First Condition of Equilibrium‚ Locating the Center of Gravity and Second Condition

Anti-gravity is the idea of creating a place or object that is free from the force of gravity. It does not refer to the lack of weight under gravity experienced in free fall or orbit‚ or to balancing the force of gravity with some other force‚ such as electromagnetism or aerodynamic lift. Anti-gravity is a recurring concept in science fiction. In Newton’s law of universal gravitation‚ gravity was an external force transmitted by unknown means. Under general relativity‚ anti-gravity is impossible
