Thanks a lot 256bits. I had my finger's crossed that I would be able to get an 'off the shelf' solution. It would have made my life a lot easier. The whole point of the project is to use as many off the shelf items as possible so that the user can just buy replacement parts from anywhere! I...

Thanks for the reply Danger I just found a machine with a good example of what I'm looking for. One picture shows how it is when engaged and it's disengaged in the other picture. This one is not positioned where the mechanism is. The wheels and axle turn independently, engaging it locks...

I am designing a Bale loading machine to load Small rectangular bales of 25kg. The machine will be driven by its wheels so no hydraulics and no power being drawn from the PTO. An example of one can be seen http://marongfarmmachinery.com/sales/view.php/16 I would like to put a clutch on the...

You need the time period to determine the distance. set up the equation that you gave for both waves and put the longitudinal waves times in terms of the transverse wave or vice versa. that reduces your number of unknowns to 2 then you have 2 equations with two unknowns. then it's just a matter...

Isn't that exactly what we are taught at school, university, college etc. The more you progress the more you realize all the stuff you have been leaving out of your calculations. The point is to help you grasp the concept in its simplest form to make it easier for you to apply it in reality.

Did you realize that the OP stated that both cars will "experience rolling without slipping" The whole point of this is to try and give a theoretical solution i.e. if everything was perfect

Why would you be worried about being traction limited if you have infinite grip?

I think if you can find a textbook on vehicle dynamics or one with vehicle dynamics in it you should find a more appropriate way to calculate this. When I din Mechanics 3 we were taught how to convert the cars to an equivalent moment of inertia. This enabled us to determine the "ideal case...

With all of that said: Is it possible for the front wheels on an FWD to lift completely off the ground under acceleration? I know they won't stay in the air for long.

if the force is applied in the same manner as you hitting the box them the force becomes an impulse. Think about it- if you strike a ball with a bat the ball changes direction immediately and the rest of the bat's swing ends not include the ball. If the force is applied gradually then the...

I would Love to be a psychologist; I believe that was actually my calling and I made a mistake by becoming a technologist. Jeremy Clarkson's job, BMW's test driver. I saw an Engineer once at a one automobile production plant whose job way to test cars on a dyno and collect data. The tests...

Lets work from the bottom up The action reaction pair. Action: The force due to gravity and the force that cause acceleration Reaction: the force from the scale keeping the object stationary This action reaction (equal and opposite reaction) theory only applies to objects that are not...

You should do a little bit of reading on open circuit and closed circuit current of a transformer. Andrew explained this very well. The transformer transforms Voltage, not current. The current is dependent on the load in the secondary side. A good way to approach it is. 1st determine what the...

I agree. The trick is in the english not the actual physics. This is the type of question my friend used to call "curve balls" when we were still studying. The answer is that it remains the same and it only depends on the two heights.

that is the very reason why safety factors are used. Nothing made by a human being is perfect. Are you sure you Diego't get fatigue failure? I ask because fatigue can result in sudden failure. I would also use a safety factor of one for your situation but that would only give the ideal load...
