Is there a specific equation or a method to determine the strength, thickness and other dimensions of a circular plate (cam plate) under axial loading and supported at the center of the circular plate (i.e. with a bolt)? How can we find the bending and deflection of such cases??

How many degree of freedom does a Hook joint have?

Ah, nope an Alternator; converts mechanical into electrical energy.

Can anyone help me with some tips to get the output current from a 'Moving coil' Linear alternator?

I am interested in designing a linear generator (miniature generator)of about 200 W, I would be really thankful if anyone could guide me with selecting the necessary permanent magnets and the coil, in order to achieve this. I have thought of a Halbach array magnet arrangement but I do have...

Hooking up an alternator or a dynamo you can produce electricity, what if several alternators are used for a single bicycle, is it possible to increase the current generated?

Edstainless, Thanks alot!

Yeah, i asked about Independent Coasting, but there is a difference between Independent pedaling and independent coasting? Yeh, i'm gonna invent one, if there isn't one..

Could someone help me with how 'Independent Pedaling System' in a tandem bike works, there are two mechanisms I know of, the Da Vinci's tandem and the Afar IPS. I know that coasting is possible with the uni-directional bearing that they have used, but how is Independent pedaling possible???

drawoh, yeah, they are turning at different speeds, and the differential won't work, coz there has to be a constant ratio between the two inputs. gruntguru, Sorry about the sketch, yeah there has to be an output shaft from the combining mechanism unit.

I'm just hopping to combine two bikes mechanically, to get a single output

Hmm.. I just have a rough idea.. Something like this

Is there a possible mechanism to combine two shafts which drive at different speeds, even with different torque ratios?

Cool.. thanks!

Referring to what JStephen Said; should it necessarily be the same speed while pedaling?

Can someone help me with some links to learn the drive mechanism of the 'Da vinci's independent coasting system' and/ or any other available independent pedaling or coasting system.

gruntguru was right. I was referring to a gym, sorry I wasn't very specific at first. Storage of water would also be an good idea, though would it be cost efficient to connect a machine a piece to a pump?? Plus, what I want is to combine several bikes, mechanically; will a power split device...

Thanks a lot for all those tips and the silly stuff as well.
