Hello all, With all-electric car designs becoming more popular, I was wondering if it was really necessary to have all that mechanical linkage in the front of an automobile to steer. Assuming independent electric motors for each wheel, and drive-by-wire technology, a simple alteration in...

http://news.yahoo.com/s/ap/20090330/ap_on_go_pr_wh/obama_autos Is this a good or bad thing? Will this solve the U.S. economic problems, or make them worse? Anything is fair game...

Homework Statement The force felt on an auto due to its movement through still air varies approx. as the square of the car's speed. (the force is also known as air resistance) assume the force varies exactly as the square of the speed. around town at 30mi/hr a car experiences an air resistance...

I have done a little research on this, but i can't find any depth information on what is the major difference between an Aero and Auto diesel? Any technical explanation on why the Aero is better than the auto? abvious is needs to be more reliable, but any answers to the why its more reliable...

I was hoping someone else may have had this issue. I have a Dodge Stratus with an AC problem. This one is kinda strange and have never had a car do this before. It cools just fine the only problem is that the AC control won't switch the fan from defrost to panel. Sometimes if I leave it on...

Why can't we improve the efficiency (miles/gallon) of ICE autos? It seems to me there are two areas that can be used to add efficiency: 1) Heat recovery with some form of a "bottoming cycle" to generate additional torque or electricity from heat lost in the radiator, and 2) Breaking...

hello every one! due to frequent power outages in my area, the lan switches at different locations stop working. so either the light is out or the switch is not working which is really irritating. so can some one help me with a circuit that can supply 6 volts for the switch in case of...

Just in case anyone has personal experience: This pertains to a early 90s buick regal with the 3.8L V6. I know there are a couple of gearheads on here and engineers but I didn't want to relegate this to one of the engineering forums so here goes. I'm trying to help a friend whose oil cooler...

Folks This is my first post to Physics Forum. I've started a project to put air conditioning into my '86 Westfalia van. The stock AC never worked and was ill-designed with huge long runs of tubing back and forth in the van, so I've removed it. I located the smallest possible 115 V AC window...

On all the auto specifications card that I read, they mention 'bhp', which i guess is the power provided by the engine, when none of the transmission losses are counted. But, is the power of a engine constant? Secondly, the also provide a specification 'Torque @ a certain rpm'. But, isn't...

Which metallic material will have a maintenance free shine when polished? I want to machine auto emblems so I'm looking for a material that does not go dull when expose to the elements. Thanks!

In a low voltage substation, including two incomings and a coupling circuit breakers, incoming C.Bs are connected to two individual power transformers which are fed from upstream medium voltage system. The two low voltage bus bars are equipped by a fast auto transfer system which is considered...

Homework Statement Skid marks at auto accidents are used to reconstruct traffic accidents. In this particular scenario, a truck of mass 1750kg moving with a velocity of (22m/s, 90 degrees) collided with a sports car of mass 1025 kg moving with an unknown velocity. After the collision, the...

Homework Statement A car traveling at 20 m/s stops in a distance of 50m. Assume that the acceleration is constant. The coefficients of friction between a passenger and the seat are u_s = 0.5 and u_k = 0.3. Will a 70 kg passenger slide off the seat if not wearing a seat belt? Prove it...

I hope you will indulge me for a rather strange request, but does anyone out there know of any wind-up motors large enough to move a small auto. It doesn't need great capacity, but i am hoping for at least the capability to move the vehicle a mile or so. Thanks, KM

High...I'm a hardy Minnesotan which also means I go through some harsh winters. The ice on my car always freezes pretty thick at school. That being said, I want to invent some sort of cool-looking low-heat flame device to basicaly melt the ice very very fast. So I was wondering: 1. What...
