WHAT IS TORQUE? Torque is a measure of how much a force acting on an object causes that object to rotate. The object rotates about an axis‚ which we will call the pivot point‚ and will label ’O ’. We will call the force ’F ’. The distance from the pivot point to the point where the force acts is called the moment arm‚ and is denoted by ’r ’. Note that this distance‚ ’r ’‚ is also a vector‚ and points from the axis of rotation to the point where the force acts. (Refer to Figure 1 for a pictoral

Chapter 24 Industry Comes of Age The Iron Colt Becomes an Iron Horse * After Lincolns death in 1865 the railroad production went up and by the 1900s it had gone up by at least 192‚556 miles * In 1862 congress began to advance liberal money loans to 2 favored cross continent companies and gave them a lot of acres paralleling the tracks. Washington gave the railroads 155‚504‚994 acres & the western states contributed 49 million more. * Land grants to railroads were made in broad belts

Chemical Kinetics‚ A Clock Reaction Abstract The purpose for the experiment Chemical Kinetics‚ a clock reaction is to figure out the reaction rate of a solution regarding its concentration‚ temperature‚ and also determine the effects of when a catalyst is present. The experiment resulted that the concentration‚ as well as its temperature can affect the rate constant inversely the outcome of the rate constant. By conducting the experiment‚ it is also discovered that the rate order of the reaction

This section will explore the concept of the iron triangle and related terms such as pork barrel politics. This thesis will look into the debates surrounding the concept of the iron triangle in the next chapter. In this section it will be explored what the nature of the iron triangle is‚ how it came into being and what kind of effect it had on Japanese society. The iron triangle First‚ we need to establish what the concept of the iron triangle entails. Japan rebuilt its economy after the Second

History of Iron and Steel I have researched the origin of hot metal cars for many years. In the very early years of iron production and later steel production historical is sketchy at best. Almost in plant equipment was built on sight and sometimes no drawings were used. The ability of American fabricators in the late 1700 and the 1800 amazes me. A case in point is Otto Mears a German immigrant that built most of the three foot gauge railroads in the Colorado Rockies. He had a third grade education

A clothing iron‚ also called a flatiron or simply an iron‚ is a small appliance: a handheld piece of equipment with a flat‚ roughly triangular surface that‚ when heated‚ is used to press clothes to remove creases. It is named for the metal of which the device is commonly made‚ and the use of it is generally called ironing. Ironing works by loosening the ties between the long chains of molecules that exist in polymer fiber materials. With the heat and the weight of the ironing plate‚ the fibers are
