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

The atlantic slave trade between western Europe and the Caribbean happened throughout the time period of 1440 to 1700. During this time Europeans were moving and settling in the Caribbean and they needed laborers to help tend to land. Which created the atlantic slave trade.This vast trade route expanded across the atlantic and left staples on both the Americas and western Europe. All the trading and interaction with new civilizations led to inflation of european currency‚ spread of foreign diseases

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

After times of famine‚ war and economic dislocation‚ poverty increased with close to 80 percent of a region’s population was faced with possible starvation each day while almost 50 percent of Europe’s population were living on the subsistence level‚ barely having enough food and shelter to survive.

Western civilization changed dramatically between 1450 and 1750. While remaining an agricultural society‚ the West became very commercially active and developed a strong manufacturing sector.
