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

Between 1450 and 1700‚ attitudes toward the European poor changed dynamically‚ roughly following a three-part cycle. In the late 1400’s‚ the poor were regarded with sympathy and compassion; generous aid from both public and religious institutions was common.

Changes in the European Economy Due to the voyages of exploration and the colonization in the Americas and all over the world‚ the European economy changed drastically from 1450 to 1700. In Spain inflation lead to economic problems‚ while in the Netherlands‚ the Dutch East India Company flourished their economy‚ and in all of Europe‚ the merchant class grew due to mercantilism. The increase of business and hauls of gold and silver lead to inflation in Spain. Inflation is the decline in the value

During the mid 15th century to the early 18th century almost half of Europe’s total population could be considered poor and destitute. The attitudes of the clergy and the attitudes of the socially elite toward these people varied from pity to disgust‚ and their proposed solution to these problems differed. Some suggested helping all of the poor by giving them alms‚ some warned others to be careful of whom the money was given to and some people believed that being poor was a voluntary decision and

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

Analyze the changes in the European economy from about 1450 to 1700 brought about by the voyages of exploration and colonization. European economy had several changes after the age of discovery. In Spain‚ there was an inflation of the price‚ which declined its economy. In Netherlands‚ they established West and East Indies Company‚ which improved Netherlands’ economy. In Portugal‚ the economy improved because of flow of gold into the Portugal. Spanish explorer found gold mines in Zactecas 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. The attitudes of those in the middle class and the more elite ranged from pity to distaste‚ proposing different solutions like punishing the poor‚ regulating them‚ or giving them help out of sympathy.

On one hand‚ continental Europe was recovering from the somewhat devastating consequences of the Napoleonic Wars‚ which disrupted trade as a result of the British blockade and left poverty in its wake. Simultaneously‚ countries such as Britain and the Netherlands were thriving‚ unaffected for the most part. Europe had experienced a surge in population
