Performance Measurement: One Sample Framework for Selecting Measurements. Â© Copyright Carter McNamara, MBA, PhD, Authenticity Consulting, LLC. Organizations try to manage the performance of each employee, team and process and even of the organization itself. The performance management process is very similar, regardless of where it is applied.
A trebuchet tends to be easier to build because it consists simply of a pivoting beam and a counterweight that rotates the beam through an arc. Catapults can launch things a fair distance -- 500 to 1,000 feet (150 to 300 meters) is common. It is surprising how much energy they can store. The gears are important, because they create a winch. The winch allows a person to put a great deal of energy into the catapult over a period of time.
Ever since they were invented, catapults have been a deadly war weapon. The catapult was invented by Dionysius of Syracuse around 400 B.C. In Greek, the word catapult means to throw into. When he designed the catapult, Dionysius wanted to create an effective war weapon. The first catapult designed worked like a crossbow. To be able to make the catapult more powerful, it was made larger and stronger and set on a tripod.
