Although I’m an Principle of Work. We’ll work with his today, and we’ll introduce a unit of measurement used to quantify formula known as the work .Newton , that is, the amount of dynamic energy available to influence the movement of an object, and is calculated by the formula,work
where .Newton In the image below, was obtained by way of direct personal experience working in my own garden. I’ve found that it takes approximately 40 pounds of force to push a wheelbarrow loaded with dirt across level ground. Because one pound of force is equal to 4.45 NewtonsNewtons the amount of force I exerted is expressed as,,[40
If 178 performed is expressed as,work
Next time we’ll explore the special relationship between .workCopyright 2015 – Philip J. O’Keefe, PE Engineering Expert Witness Blog ____________________________________ |
