The Fulcrum and the Lever Essays - 2653 Words

I turn the key and unlock the deadbolt. It’s been a long day’s work. I have been working three jobs for weeks now. I come through the door of my tiny one-bedroom house and stare at the desk, piled high with debris: old junk mail, magazines, and a few bills. I keep thinking maybe on my day off I’ll clean this mess up, balance my check book and pay my bills. â€Å"But what’s the use?† I think to myself, â€Å"I have $210 left on my credit card, that’ll get me through another week.† Independence is what I wanted and that’s what I got. I have a car, a house, furniture, stocked cupboards, and plenty of I-can-do-what-I-want free will. I was working a lot, and sure was doling out a lot of dough, yet I felt atrophy kicking in. When I was dying to leave my†¦show more content†¦This is how the wealthy really build their wealth. Debt is dumb. Welcome to the real world! He also speaks of the eternal car payment, saying, â€Å"Most people carry a car note for their entire lives, paying about $378 a month. That same amount invested from age 25 to retirement would, on average, amount to more than $4 million by age 65. You do the math.† Americans do not stop and think of how all of this debt they are carrying hinders their freedom to be wealthy, safe and have peace of mind. nbsp;nbsp;nbsp;nbsp;nbsp;Darren Waggoner of Credit amp; Collections World says, â€Å"Theres little doubt Americans 18-to-34-years-old are addicted to plastic. Many are burdened with hefty student debts, too. Struggling to keep from sinking deeper into a financial abyss, they often turn to credit cards to bail them out. They dont understand that their buy-today, pay-whenever behavior could doom them to a lifetime of debt (21).† This is yet another example of how prevalent the problem is. Richard Sylla, writer for the Houghton Mifflin Company says, â€Å"When the national debt was created in its current form in 1791, it stood at $75 million. Nearly two centuries later in 1988, the debt stood at $2,600.8 billion. It’s amazing toShow MoreRelatedWork Is Calculated As Force X Distance1586 Words   |  7 Pagesfits tightly. d. The lever.

Answer 2: Below is the method to find ideal mechanical advantage of four types of simple machines: a. Inclined plane: The ideal mechanical advantage of an inclined plane can be determined by the below formula: Ideal mechanical advantage = Length of Incline à · Height of incline b.

Equipment Meter stick (1) - no metal ends Fulcrum (1) Clamps (4) Weight Hanger (1) Mass Set (1) Digital Scale (1) Theory For a body to be in static equilibrium, two conditions have to be met: ÃŽ £F = 0 and ÃŽ £Ãâ€ž = 0 where F is force and Ï„ is torque. (The torque is the force times the lever arm, r) The first condition, ÃŽ £F = 0, is concerned with translational equilibrium and ensures that the object is at rest or isRead MoreSimple Machines Make Work Easier2272 Words   |  9 Pagesmachines. IMA (or ideal mechanical advantage) depends on the type of machine. The general idea of IMA is to divide some kind of input distance by the output distance, but the specifics of the type of distance are varied. For example, the equation for lever IMA is IMA = l_i/l_o . Along with the mechanical advantage, a machine can be a multiplier and divider. A force multiplier means that the output force will be larger than the input force. Force multipliers also can be called speed/displacement dividersRead MoreUsing A Tool Of Stem Innovation1613 Words   |  7 Pagesinnovation could be? It was the wheel barrow, now I know what you are saying, â€Å"The wheelbarrow isn’t a lever!† Actually the whee l barrow is an innovation of the lever because it has the components of a fulcrum, load, and effort force which is exerted. The wheelbarrow falls under first-class lever because the fulcrum placed between the load and effort to give it equal balance according www.ohio.edu. The lever is one of the simplest mechanical devices ever and has made life so much easier in society.

Was it just a symbol of power or was it also a way to reach the Gods in death? While no one can be sure how and why exactly the pyramids were built, through the examination of the theory given by Peter Hodges, as the lever theory, and of Mark Lehner, with the ramp theory, it is seeming to be more evident that Khufu’s Great Pyramid in Giza was built using extensive manpower and the use of ramps. The people of Egypt have long stressed the importance of the afterlife throughRead Morescience of catapults790 Words   |  4 Pagespotential and kinetic energy. The ball keeps bouncing and transforming energy until it finally comes to a stop. Our Catapult is also a first class lever. As you can see in this illustration, the ball is the load, the fulcrum is where the pipe is connected to the center block of wood and the input force is the bungee cords. A first class lever has the fulcrum between the input and the output force. I said earlier the bungee cords have potential energy. When the pipe is released the force of the bungeeRead MoreKINE 1301 Essay1593 Words   |  7 Pagesworkers’ compensation and disability-related costs. Reduce injuries.

A lever system is a mechanical device that makes moving weight or load easier to move. It can be described as any rigid bar free to turn about a fixed point called a fulcrum (Thibodeau, patton 2003). The bones acts as the lever while the joints acts as the fulcrum to the lever. The bone moves around its joint fulcrum due to the contracting muscle applying a pulling force on a bone lever at the point of the muscle’s attachment to the bone. There are three different classes of levers, the firstRead MoreKinematics: Simple Machine and Prime Mover2581 Words   |  11 PagesRenaissance scientists: †¢ Lever †¢ Wheel and axle †¢ Pulley †¢ Inclined plane †¢ Wedge †¢ Screw They are the elementary building blocks of which all complicated machines are composed. For example, wheels, levers, and pulleys are all used in the mechanism of a bicycle. Simple machines fall into two classes; those dependent on the vector resolution of forces (inclined plane, wedge, screw) and those in which there is an equilibrium of torques (lever, pulley, wheel).

Projectile-throwing machines are found in three main categories: the catapult, the ballista, and the trebuchet (How Stuff Works). The catapult has a lever arm attached to a â€Å"bucket† that is usually pulled back by rope and the projectile is released when the rope is cut (How Stuff Works). The ballista is basically a giant crossbow and the trebuchet is similar to the catapult but is a weighted beam with
