Flywheel Definition and 264 Threads

It's come upon my interest that besides capacitors, flywheels can also be used to store considerable amounts of energy at impressive levels. The best material is supposedly carbon fiber, since it can spin at high speeds. But what about other materials like steel fibers or fiberglass? Those...

Hi, A flywheel with a diameter of 1.2 m is rotating at an angular speed of 200 revs/min What is the angular speed of the flywheel in radians per second? Would I just do this? 200 revs/min = 3.33 revs/sec 3.33 revs/sec = 6.66(pi)rads - - - answer?

The flywheel of a steam engine begins to rotate from rest with a constant angular acceleration of 1.33 rad/s2. It accelerates for 23.5 s, then maintains a constant angular velocity. Calculate the total angle through which the wheel has turned 48.7 s after it begins rotating. \omega = \omega _...

hi all! Are composites like carbon fibres (CFRP) the best material for flywheel? There is no doubt on its high strength to density ratio. Regarding the safety consideration, is flywheel made of composites safer than that made of other materials? I've read through some articles claiming that...

Flywheels are interesting but dangerous if they malfunction because the energy is concentrated in the vicinity of the rotor. My question to you ME's is this- could you engineer a practical and/or efficient energy storage system that relied on gravity? I envision an enourmous mass on a...

What is energy?How a flywheel stores energy? What is the physics behind that?

Question: A flywheel 0.600 m in diameter pivots on a horizontal axis. A rope is wrapped around the outside of the flywheel, and a steady pull of 40.0 N is exerted on the rope. The flywheel starts from rest, and 5.00 m of rope are unwound in 2.00 s. Okay i have tried finding the angular...

"A flywheel 0.600 m in diameter pivots on a horizontal axis. A rope is wrapped around the outside of the flywheel, and a steady pull of 40.0 N is exerted on the rope. The flywheel starts from rest, and 5.00 m of rope are unwound in 2.00 s. 1. What is the angular acceleration of the flywheel?"...

now i get the formula I = mr^2 [n2/(n1+n2)] [(gt^2)/(2h) - 1] where m = mass of the hanging wieght; r = radius; n1 = no. of revolutions before the weight reaches the floor; n2 = no. of revolutions before the flywheel stops; t = time taken for the weight to reach the floor; h = height of...

I need help figuring out how much HP/TQ is freed up by changing to a lighter flywheel in a car. Specifically the Mazda KLDE/KLO3 2.5L V6 found in the Ford Probe/Mazda MX6. I have listed all needed specifications (I hope). Basically I enjoy physics but am not smart enough to identify and...

Hi people. I wonder if anyone could check a problem I had been set as homework and [possibly point me in the right direction for the second part. A solid disc flywheel, mass 900kg, 0.75m radius accelerated at 0.8rads/s(sq) from rest to 480 RPM in 63 secs. a) Calculate the number of...

Ok, did I do this correctly? The question goes: Determine the angular velocity and angular acceleration of the disk and the link AB at the instant A rotates through 90 degrees. See attachment for the figure. What I did--first the disk: Assuming \alpha_{disk} is constant...

I missed a week of school so I'm a bit behind, i do have a book so i need just a bit of guidance. Any extra help would be appreciated. Question Part 1 The flywheel of a steam engine runs with a constant angular speed of 115 rev/min. When steam is shut off, the friction of the bearings and...
