Increase efficiency of rotating shaft.
I am mechanical engineering student . I described one mechanical
engineering situation that is very useful in any kind of mechanical and energy consumed industries. It it is not even in any applied mechanics book. I hope you will try to understand it and use it. Plz visit my website http://energyefficiency.zoomshare.com Jigar Patel |

Plz visit my website http://energyefficiency.zoomshare.com Jigar Patel This is the stupidest thing i've seen in quite some time. Case 1 uses the energy of the falling plate to offset the work being done but ignores energy needed to raise the plate to begin with. While it indeed may take less energy to spin the shafts in the former case, the overall work is a wash. It's entirely analogous to a pulley with a rope over it with weights on both ends. If the weights on the ends of the rope are equal, then yes it takes less work to rotate the pulley than if all the weight was at one end of the rope, but raising in one case you've done some work, and the other you've accomplished nothing. |

This comes from a failure to understand the forces involved. Assuming
that it is equilibrium the load from the weighted plate will be transferred to the pulleys at right angles to the plane of contact. This plane of contact will be the circumference of the pulley, and any force at right angles to it will pass through the pulley centres and no moment (torque) will be generated. If it is not balanced and in equilibrium, both pulleys will spin briefly in the same direction when the plate and weights fall noisily between them to the floor. You will have been much better off just pulling the thing. Basically somebody got their calcs wrong and thought they'd found free energy.

A weight resting on a pully helps spin it? No.
The weight plate will make it harder to spin the pully, because of friction both at the interface between the weight and the pully, and increased load on the pully bearing. A stationary object can't impart an angular acceleration on a spinning object. "jigar" wrote in message oups.com... I am mechanical engineering student .

Well this guy is a foreign engineering student living in India. I really
hope they graduate MANY full fledged engineers having his incredibly revolutionary viewpoint. I also hope he rises to manage a large staff of like minded souls with a huge budget. This will help balance the global asskicking the low buck offshore corporations are giving the rest of the world. Let them focus on low cost highly innovative products like this one, and let the rest of us focus on accuracy and quality. -- Have a great day Scott "Canalbuilder" wrote in message news This comes from a failure to understand the forces involved.

Wow... Lab work so bad that it isn't even wrong. Don Lancaster would be
so proud! |

"Pulleys are designed so that from points a and a` to points b and b`, radii of pulleys continuously decrease." The "Case 2" pulleys are like cam lobes, and the plane of contact isn't perpendicular to the radius. But, as Ron says, Jigar ignores energy needed to raise the plate. |
