OK My electric racing car

https://www.instructables.com/id/Building-an-electr...

Weighed around 100Kg but would go at 50 KPH

The electric motor was 500 watts at 24 volts, about 2/3 Hp.

Select the right gearing for your required speed and this will easily move your 200Kg at 5K/h which is about walking pace.

Even a small Hp petrol engine would - say 4 Hp like my lawn mower.

The key is getting the gearing right. Build light but strong enough.

sir thanks for your feedback...kindly guide me about gear box system and mechanical model to build this...i have 300$ for this project.

Fixed gear 14:1 for a motor doing 2000 RPM and a 10 inch wheel diameter.

I recommend you read the instructable I linked to.

This vehicle was designed to travel at 50 KPH and for 4 hours so has a different purpose to your needs BUT the principles apply.

YOU will need to experiment and work out your required gear ratio.

If you need specs like this you might want to check the car build for the great solar races here in Australia.
I see no realistic change to do that on batteries as you always fight the weight of the batteries too.
Only chance that might work would be to use really fast motors and a massive gear reduction.

Yeh you have to get the gearing right. the contest we entered is a limited motor contest so everyone has to use the supplied motor and batteries. Lots and lots of people burn the motors out by upping the gear ratio to make the car go faster. Even those who fitted gear boxes didn't really gain much. It has a very narrow window of effeciency.

Does it strike you that

a) we don't know where in the world you are.

b) what sort of supplies you might have access to

c) what sort of motor your talking about

d) the sort of terrain you want this to work over

e) how well or skillfully your going to build this cart. poor building = friction and loss of power.

f) how much your willing to pay for the said motor.

Your use of relatively scientific terminology suggest strongly an educational problem set as a hypothetical question rather than a practical problem. I would have thought if you comfortable and familiar with Newtons, and m/sec you would be able to estimate an answer your self most people would be thinking in terms of walking pace, MpPHand weight, Kg.

i.e." I need to move feed for my cattle in 200 KG bags on a cart at roughly walking pace how can I best do this using an electric motor. The cart will be built out of wood and I have found 4 wheelbarrow wheels to put on it."

So apply what you have been told so far some simple maths should get you close enough to make some experiments work.

Really you need to have an answer to ALL the questions I asked before you start designing or you will be wasting your time.

Newtons are a measure of force.

Sounds like homework.

Yup, and therefore can be used as a measure of weight (F = ma, W = mg :-). I've never encountered such a usage outside of homework, though...

Just had a thought:
Can't we add another category for the flag button?
To the additional spam, not nice and so...
Something like "Homework/School project".
This way it could all be moved into a school section with teacher access.
Maybe then some of their teachers would start to do our work LOL

If it is homework use Google, same for a project.
This already helps you define the question for the problem better than copy and paste from the book.
In case it is no homework provide the missing details on the machinery involved as there are literally thausands of motors for this to chose from.
