definition of braking efficiency?

Question

braking system for motorvehicle

Answer 1

The force the brakes can make as a percentage of the gross vehicle weight. Needs to be 50% for an mot, so the brakes would have to have a combined force (all 4 wheels) of 700Kg on a vehicle which had a gross weight of 1400Kg.

Answer 2

hmm....they allow you stop in a short distance. The shorter the distance, the more efficient the brakes are. The longer the distance, the the less efficient the brakes are.

Answer 3

Basically, a hybrid electric vehicle combines an internal combustion engine and an electric motor powered by batteries, merging the best features of today's combustion engine cars and electric vehicles. The combination allows the electric motor and batteries to help the conventional engine operate more efficiently, cutting down on fuel use. Meanwhile, the gasoline-fueled combustion engine overcomes the limited driving range of an electric vehicle. In the end, this hybridization gives you the ability to drive 500 miles or more using less fuel and never having to plug in for recharging.

Answer 4

ef·fi·cien·cy

1. the state or quality of being efficient; competency in performance.

2. accomplishment of or ability to accomplish a job with a minimum expenditure of time and effort: The assembly line increased industry's efficiency.

3. the ratio of the work done or energy developed by a machine, engine, etc., to the energy supplied to it, usually expressed as a percentage.

Answer 5

Directly proportional to the heat dissipation when the brakes are applied . Sometimes called energy absorption.

Answer 6

Apply brakes and stop - efficient!
Apply brakes and don't stop - inefficient

Simple really

Answer 7

The coefficient of friction = Load over area

Answer 8

Anything you can walk away from.
