ω₁ = sqrt((2*KE/I)+ω₂^2)
This formula uses 1 Functions, 4 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Initial Angular Velocity of Braked System - (Measured in Radian per Second) - Initial Angular Velocity of Braked System is the velocity at which the system or the object is rotating before the brakes are applied.
Kinetic Energy Absorbed by Brake - (Measured in Joule) - Kinetic Energy Absorbed by Brake is defined as the energy absorbed by the braking system.
Moment of Inertia of Braked Assembly - (Measured in Kilogram Square Meter) - Moment of Inertia of Braked Assembly is the measure of the resistance of a body to angular acceleration about a given axis.
Final Angular Velocity of Braked System - (Measured in Radian per Second) - Final Angular Velocity of Braked System is the velocity at which the system or the object is rotating after the brakes are totally applied.

STEP 1: Convert Input(s) to Base Unit

Kinetic Energy Absorbed by Brake: 94950 Joule --> 94950 Joule No Conversion Required
Moment of Inertia of Braked Assembly: 141.4 Kilogram Square Meter --> 141.4 Kilogram Square Meter No Conversion Required
Final Angular Velocity of Braked System: 0.52 Radian per Second --> 0.52 Radian per Second No Conversion Required

Define Kinetic Energy?

To accelerate an object we have to apply force. To apply force, we need to do work. When work is done on an object, energy is transferred and the object moves with a new constant speed. The energy that is transferred is known as kinetic energy and it depends on the mass and speed achieved.
