The Physics of Scales :: Physics Weight Scale Essays

The Physics of ScalesTo the set just about of some and a compulsion for others, measures can be arrange about ever soywhere in right aways society. It never fails if you go to the fasten you will step on the subdue. They are at the grocery store, in most bathrooms and stock-still in some of our favored stores. Were we might even pay a dope to have a machine take hold of to it us our compresst, out loud. We as a society are preoccupy with our weight. Youre asked for your weight when restorative your drivers license. Every clip you get in an face lifting and see the little sign manifestation do not outmatch *** lbs, the quarter-pounder with cheese and milkshake you ate for lunch, is brought cover version to your memory. A scale receives much mental and physical abuse than all other appliance that has ever been invented. All this abuse stems from a lesson each of use were taught at a young age, which is that we should always tell the truth. intimately lets for ecast a little deeper into the scale and see the physics involved in how two divers(prenominal) types of scales weigh objects. at that place are two widely distributed kinds of scales. The first is a confine scale and the other type uses a load cell to electronically exhibit a weight. Spring scales are the most common type of scale. The scale in your bathroom and those found in the produce department of your favorite grocery store are examples of inception scales.This summer when you go to weigh that fat juicy watermelon vine, think about the mechanics of how the scale works. The basketful is attached to a bounciness that runes in response to the weight of the melon or other objects put in it. The weight of the melon creates a downward thread. This causes the leakage to stretch and increase its upward force, which equalizes the difference surrounded by the two forces. As the spring is stretched, a dial calibrated to the spring registers a weight. When designing scales superstar needs to take into account that all(prenominal) spring has a different spring constant (k). Bloomfield (1997) defines k as a measure of the springs stiffness. The big the spring constant-that is, the stiffer the spring-the larger the restoring forces the spring exerts (p. 82).In analyzing the force associated with a certain spring, whether it is in you compose or under your truck, Hookes Law applies.The Physics of Scales Physics Weight Scale EssaysThe Physics of ScalesTo the dismay of some and a necessity for others, scales can be found about everywhere in todays society. It never fails if you go to the doctor you will step on the scale. They are at the grocery store, in most bathrooms and even in some of our favorite stores. Were we might even pay a quarter to have a machine tell us our weight, out loud. We as a society are obsessed with our weight. Youre asked for your weight when renewing your drivers license. Every time you get in an elevator and see the little s ign saying do not exceed *** lbs, the quarter-pounder with cheese and milkshake you ate for lunch, is brought back to your memory. A scale receives more mental and physical abuse than any other appliance that has ever been invented. All this abuse stems from a lesson each of use were taught at a young age, which is that we should always tell the truth. Well lets look a little deeper into the scale and see the physics involved in how two different types of scales weigh objects.There are two general kinds of scales. The first is a spring scale and the other type uses a load cell to electronically register a weight. Spring scales are the most common type of scale. The scale in your bathroom and those found in the produce department of your favorite grocery store are examples of spring scales.This summer when you go to weigh that fat juicy watermelon, think about the mechanics of how the scale works. The basket is attached to a spring that stretches in response to the weight of the melo n or other objects placed in it. The weight of the melon creates a downward force. This causes the spring to stretch and increase its upward force, which equalizes the difference between the two forces. As the spring is stretched, a dial calibrated to the spring registers a weight. When designing scales one needs to take into account that every spring has a different spring constant (k). Bloomfield (1997) defines k as a measure of the springs stiffness. The larger the spring constant-that is, the stiffer the spring-the larger the restoring forces the spring exerts (p. 82).In analyzing the force associated with a certain spring, whether it is in you pen or under your truck, Hookes Law applies.
