a car with 4 sets of brakes,a truck with 10 sets of brakes ,who can stop the fastest?

Question

A car and an eighteenwheeler traveling at the same speed side by side have to stop fast which of these can get stoped th quickest

Answer 1

The car. It has less momentum and mass than the truck. It is also shorter in length.

Answer 2

This depends on a whole lot of circumstances. At what speed for instance. What is the actual weight of each vehicle? Number of tires on the road surface plust the width of the tire surface which creates friction on the road surface, are we on level roads or going uphill or downhill? What are the road conditions? gravel surface, dirt, pavement? How about weather conditions, dry surface, water covered, snow and ice covered? What is the total weight of the vehicles in question?
To assume that the car can stop faster and ina shorter distance is nothing more then a myth at best!
Driver skill has much to do with such actions.
A small car versa's a large car travelling on a paved road has 4 tires with minimum width of tire surface on the road to create friction with the road surface which is needed to stop the vehicle in the first place. To assume that a car can stop faster in a shorter distance then a truck with 10 wheels going at the same speed, under the exact same road and weather conditions is often very incorrect. The truck while weighing more, will most probably also be carrying a heavy load of which this weight will increase the tire friction area on the road surface. A truck with 10 wheel brakes will have a total of 5 axles and a total of 18 tires on the road surface. The truck driver is a skilled driver with trained skills that the average car driver does not have.

Answer 3

No, accepted braking makes use of all your brakes. in case you have a motor vehicle with an anti-grab braking gadget, pulling on the emergency brake could routinely neutralize the ABS gadget to the rear brakes(some luxurious automobiles negate this with a distinctive style e-brake.) Your accepted brakes are activated by way of hydraulic tension utilized by way of strains to your front and rear brakes. That hydraulic tension is approx. 1000 psi while the emergency brake cable pulling the two brake footwear or pads they activate could have an entire ordinary mechanical tension of perhaps 300psi (i'm close right here, its been approximately 25 years on the grounds that I studied this however the technologies is the comparable for the e- brake.) The emergency brake is meant purely to maintain your motor vehicle from shifting while this is parked or that can assist you in preventing in the journey that your significant brakes have failed. this is solid to apply your parking brake on a conventional foundation because it keeps the cable from freezing up and facilitates your brakes self adjusting function to function top.

Answer 4

You can have 600 sets of brakes but without adhesion NOTHING will stop you (like trying to stop on a frozen lake). The lightest vehicle will always stop quicker given similar tire compounds.
FYI - anti-lock brakes do NOT shorten braking distances.

Answer 5

IF the truck is empty and the car DOES NOT have anti lock brakes the truck should win, change the parameters or put a rookie driver in the truck and the car will most likely win, that's why every defencive driving instructor will tell you to NEVER cut off a semi.

Answer 6

The car will beat it in a braking duel............ less weight to bring to a halt....... just look at that new McLaren-Mercedes Supercar that's out...... they did a demonstration on TOP GEAR (http://www.topgear.com) of it stopping from 120mph in the same space a normal car can stop from 60mph

Answer 7

If the truck is empty, it will stop well before the car,if it is loaded, the car will stop much quicker.

Answer 8

a car with the disc break...try it you can tell its true

Answer 9

a car because it's ALOT lighter
