torque flywheel Q&A Review
What is the formula to calculate torque in a flywheel?
Flywheel torque means angular acceleration -I:Nm/N+n(2gh/w2-r2) Where, I = Moment of inertia of the flywheel assembly N = Number of rotation of the flywheel before it stopped m = mass of the rings n = Number of windings of the string on the axle g = Acceleration due to gravity of the environment. h = Height of the weight assembly from the ground. r = Radius of the axle.
What kind of forces, torques, are applied to an average car engine flywheel?
The flywheel is attached to the drive-shaft for the crank. There are rotational deformations due to the torsion effect of the drive moment and the inertia moment caused by the angular acceleration. The maximum stress occurs on the hub and near shaft-hole surface, however the maximum deflection is along the right outer-edge of the rim. The stress and deflection almost at any point are not constant. They are alternating transiently as the flywheel is rotating.
A flywheel has a mass of 12.5kg and a diameter of 0.30m. It's initial RPM is 90. It is then increased to 720 RPM within 8 seconds. What is the torque applied on it?
Considering the flywheel to be of disc type, we have I= mr^2/2= (12.5*0.15^2)/2= 0.140625 kg-m^2 angular acceleration, a= (w2-w1)/t w2= 2*pi*N2/60= 75.398 rad/s w1= 2*pi*N1/60= 9.425 rad/s Now we can use the formula for torque developed, T= I*a this gives, T= 0.140625*(75.398-9.425)/8 . = 1.16 N-m You will get different answer (2.32 N-m) if you consider the flywheel to be of ring type.
How is the size of a flywheel related to torque?
A flywheel is used to even out the fluctuations from a rotating shaft output. The relationship is as follows: Driving Torque= Moment of Inertia of flywheel x Angular accelaration So if we assume a constantly increasing torque, the higher the MI of flywheel, lower will be the acceleration (hence lower fluctuations). More than the size, it is the MI of the flywheel that is decisive. Putting a gear between the driver and load will change the inertia of driver shaft. So changing gear doesn't simply change the output speed, it also changes the torque. This is the reason lower gears (gear ratio high) in a car gives better towing power like hauling a heavy load or climbing a hill.
What would be the torque of a 126 kg flywheel of diameter 0.111m running at 1400 rpm?
Your question is not clear If flywheels running at constant speed I.e. there is no angular acceleration so torque becomes zero. T = moment of inertia * angular acceleration Here moment of inertia is m*r*r/2 for disk type flywheel{assuming}=126*.055*.055/2 I= 0.190kg meter square And speed is given 1400 rpm ,if it is constant then torque is zero or if flywheel attains speed in 1 sec than angular acceleration is 1400rpm per sec then we can calculate torque of flywheel by multiplying angular acceleration to moment of inertia.
When a torque is applied perpendicular to a spinning flywheel's rotation axis, why doesn't the magnitude of the flywheel's angular momentum change, only the direction of its angular momentum?
When a force acts perpendicular to an object’s linear momentum, it changes the direction of the momentum. Because a sideways force has neither a forward component (which would speed the particle up) nor a backward component (which would slow it down), it doesn’t change the object’s speed. Similarly, for a torque to change the magnitude of an object’s angular momentum, it must have a component acting in the direction of its angular momentum (i.e., along the axis of rotation.)
How does the flywheel reduce the torque required to start an Internal Combustion Engine?
The role of the flywheel in starting an engine is to carry the ring gear around its outer edge. The starter motor has a gear which engages the ring gear to rotate the flywheel. To rotate the engine to start it, the starter motor has to overcome the rotational inertia of the flywheel plus friction and inertia of the engine’s moving parts. A heavier flywheel will require more torque to get up to the starting speed of the engine. A bigger diameter flywheel would require less torque but more speed on the starter motor to start the engine.
What is the difference between a fluid flywheel and torque transmission?
Fluid flywheel has just two components an impeller and a turbine. Oil is circulated by centrifugal force to the outside diameter of which ever half is turning the fastest causing oil to spill over into the slower member and keep circulating in this manner until both halves are turning at the same speed. Solid drive occurs when the oil is basically acting as a solid and driving via the vanes on the inside of both halves. In practice there is up to 5 percent slip. They are slow to achieve a good solid drive. They were the forerunner to modern automatics used in preselector transmissions. Torqueconvertor are fluid flywheels with one additional component know as a stator. This has curved fins which direct returning oil from the outer diameter of the turbine back at the vanes by way of curved vanes to hit the rear of the impeller vanes thus assisting the impeller. A sprag clutch prevents the stator from turning backwards and once speed is achieved will turn forward in unison with the whole of the torqueconverter. Some slip still takes place but is around 2percent.
What is resisting torque in turning moment of flywheel?
When you rotate a flywheel, the torque you must apply depends on two things: how much acceleration or rate of change in rotational speed you want, and the mass of the flywheel (actually the moment of inertia, which depends on how far the mass is from the center.) Throw in some friction and air resistance if you want to be precise.
If the maximum torque of a car is 190Nm, does it mean that the flywheel can be stopped by 190N force applied at 1 meter from the center?
NO, it is not compulsory. Imagine a flywheel having a rotational speed of ,\omega , and moment of inertia ,I , then energy stored in this flywheel is given as Energy = ,\frac{1}{2},I\omega^2 ,. Therefore, energy stored in a flywheel depends on its mass, size and speed of rotation. You see that torque of an engine has nothing to do with flywheel. The function of a flywheel is to make the varying torque of engine more uniform. Anyways, in order to stop this flywheel, you must somehow dissipate all the energy stored in it. A torque can be applied in opposite direction of rotation to stop it (just like a force in opposite direction of a motion stops the motion). Therefore, to stop the flywheel Energy stored = work done by torque in opposite direction, or \frac{1}{2}I\omega^2= T\theta where T is the torque applied to stop it and ,\theta , is the amount of rotation occurred before it finally stops. Also, one cannot instantaneously stop the flywheel or else the shocks will be huge and system will fail. Therefore, time factor also plays an important role in stopping of flywheel. The more is the stopping torque, less will be the time taken to stop it.
