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.
The arm is 10 feet in length so the rads/s^2 can be multiplied by this to get a f/s^2. a = 10*100 rads/s^2 = 1000 f/s^2 Now: s = (1/2)a t^2 For s we will use the arc distance and that is 10A where A (in radians) is the angle the arm is rotated through before the projectile is released.he arm of the catapult is R=10ft long, http://www.knightsedge.com/medieval-weap... and starting from initial horizontal position it acclerates projectile at the rate s=100 rad/sÂ².
