Moment Of Inertia Of Paddle Wheel Pdf Optimal Control For Whole Body Motion Generation Using Center
Considerations of this lead to the the large radius of the paddle wheel generating a large moment.
Moment of inertia of paddle wheel. At an angular velocity of 40 rads. How can i calculate the size of paddle wheel. The pellets stick to the paddles and impart all their momentum to the wheel. 8 derived in the moment of inertia example the moment of inertia of the disk is at 5 digits therefore the moment of inertia of the disk is 1238 kgm 2.
Moment of inertia plays the role in rotational kinetics that mass inertia plays in linear kineticsboth characterize the resistance of a body to changes in its motion. Pellets with a mass of 40 g are shot from the pellet gun at a velocity of 250 ms and strike the paddles at 080 m from the center of rotation. I icg mb2 where b is the distance from the cg to the new axis the linear dimensions in this. A demonstration of measuring the moment of inertia of a bicycle wheel about a axis parallel to the axle using a rate gyro.
For slabs icg 112ma2 b2 axis theorem. Calculation of the mass and moment of inertia of the slit paddle wheel assy about its rotation axis to sc x axis eis opt desnote moislit cmb nrl 01 jul 99 dimensions from bob moyes conceptual design for rods disks icg 12mr2. I look at the books and i can not understand how to calculate and design the paddle wheel. Part a calculating the moment of inertia of the wheel.
Weight paddle wheel 11850 lbs diameter 15 velocity 1 rpm this paddle will will not impulse a boat it is only a decoration it will sit on top of two low friction bearings and it will be submerged 2ft in a small pool where two paddles will be inside the water at the same time. The area of each paddle is 22ft2 initial approach. This demonstration is perhaps. Here are some details of the paddle wheel.
The moment of inertia depends on how mass is distributed around an axis of rotation and will vary depending on the chosen axis. Discussion in hydrodynamics and aerodynamics started by refael jan 15. How can i calculate the size of the paddle wheel. Three wheels of equal mass but different moments of inertia are mounted so that you can spin them by twisting the rods that run through their centers.
Having said that suppose the vanes this is the correct fluid dynamics word for the paddles have wetted area a in the sream flow of velocity v and move with tangential velocity v in the direction of the stream. The acceleration continues until the paddle wheel attains an angular momentum of 200 kg m2 s.
