whistler So by resolving parallel to the hill, the max angle a car could climb at a constant velocity is when $$ N \mu_{s} = N\mu_{k} + mgsin\theta $$ Because $ N = mgcos\theta $ , the equation can be re-arranged to give $$ tan\theta = \mu_{s} - \mu_{k} $$ mikelocke

holz.box Slope cars are installed in more than 80 places in Japan and South Korea. Good luck (momentum) may carry you up the slope to an extent, but eventually luck will run out if not accompanied by work. holz.box No problem with slopes.Not directly related to your question. The Engine has to exert additional power only if it has to accelerate the car to a higher velocity. Since this mode of transportation is relatively unknown, it lacks widely accepted generic name, other than the simple "monorail". instead, we get the disco (which looks like a clown car) and the freelander, which looks worse than the p.t. It's funny that how optical illusions can defy scientific explanations.This thread gave me a new information - "gravity hill". is the answer. Full length 18 wheel tractor-trailer rigs have trouble and I have seen one slide backwards down the hill.

that's what my local land rover dealer told me. the defender stopped sales in the u.s. in 1998 due to regulations requiring air bags for both passengers and stricter side impact requirements, which couldn't be implemented without a major design change. Any idea about such roads in India? Re: Maximum Steepness A Car Can Climb 12/27/2009 1:50 PM A life time of living out in the country has shown me that rear wheel drive climbs hills much better than front wheel drive. CA SR-4 has a claimed maximum slope of 24%. It's funny that how optical illusions can defy scientific explanations.Interesting topic. Any idea about such roads in India? A small economy car can negotiate either of these roads, as can a pickup truck with a 2400 pound slide-in camper on top and I have seen a large 5th wheel towed by a pickup truck navigate SR-108 at a substantial speed. You might like to read one of a very very interesting phenomenons called "gravity hill" - more of an optical illusion that makes it appear defying gravity.Unlike internal combustion engines, electric motors and external combustion engines (like steam locomotives) generate the maximum design torque from the get-go. An important criterion in car design is the maximum slope that a car can climb. Never knew about it before. In the diagram below the car is moving up the hill. California State Route 108 claims to have a maximum slope of 26%. laistm

I think smartcat's RC car shows that just like in any other field of life, it's very difficult to get to the top. whistler

n_ A small economy car can negotiate either of these roads, as can a pickup truck with a 2400 pound slide-in camper on top and I have seen a large 5th wheel towed by a pickup truck navigate SR-108 at a substantial speed. But, it's very easy to go downhill le bossman

You need to have sufficient inner drive or you won't make it. But the topic does remind of it.

the emissions for the defender are slightly better than the hummer, unfortuantely.Sorry I'm not a fan of the Hummer it was the first thing that came to mind!the codes i refered to say not more than 1 in 8 but i was wondering if a 1 in 6 slope will work?just because you 'could' build it, it would be awful and un-usable.
