mass of object, it's shape and relative point of rotation - the Radius of Gyration. Linear and angular (rotation) acceleration, velocity, speed and distance.įorces acting a very short time are called impulse forces.Įnergy possessed by an object's motion is kinetic energy. power and torque.īelt Transmissions - Speed and Length of BeltsĬalculate length and speed of belt and belt gearing.Įnergy density - by weight and volume - for some ways to store energy Motion - velocity and acceleration, forces and torque.įorces, acceleration, displacement, vectors, motion, momentum, energy of objects and more.Īngular velocity and acceleration vs. The kinetic energy of the rotating bicycle wheel can then be calculated to Ω = (3.32 revolutions/s) (2 π rad/ revolution) The angular velocity of the wheel can be calculated as The wheel circular velocity (rps, revolutions/s) - n rps- can be calculated as The speed of the bicycle is 25 km/h ( 6.94 m/s). The Moment of Inertia for the wheel can be calculated The weight of the wheel with the tire is 2.3 kg and the inertial constant is k = 1. For our calculation we approximate the radius - r - of the wheel to The term maraging is derived from the strengthening mechanism, which is transforming the alloy to martensite with subsequent age hardening.Įxample - Energy in a Rotating Bicycle WheelĪ typical 26-inch bicycle wheel rim has a diameter of 559 mm (22.0") and an outside tire diameter of about 26.2" (665 mm).
