Calculate Energy To Weight Ratios In Automobiles

These recycling facilities typically weigh a vehicle with the recycled materials yet loaded onto the vehicle, then weigh the vehicle once the materials bear been unloaded to impel the weight of the recycled facts. Descant to the manager of the recycling plant to find out if the vehicle can be weighed by itself.2.


Instructions


1. Degree the weight of the vehicle. Many truck-stop scales Testament weigh the vehicle, as Testament some capacious recycling facilities.

A vehicle's knack to arrive a obsessed distance at a specified date depends on the vehicle's weight and its bent. "Bent" is defined as either the size of horsepower the engine produces, or the vastness of torque produced. Provided the engine's potentiality output is increased and the vehicle's weight is the identical, the vehicle will be quicker. Whether the engine's competence is fixed however the vehicle's weight is reduced, the vehicle Testament further be quicker. The converse of these principals is extremely genuine.


Measure the engine's power output using a dynometer. A dynometer is an instrument which measures both the torque and horsepower produced by an engine. It also specifies at which RPMs the engine produces the maximum amount of power. The automobile is actually driven onto the dynometer, which allows the rear wheels to spin while the automobile stays stationary. Dynometers are extremely expensive instruments to purchase. However, most race-engine modification shops have dynometers and can test your automobile's power output for you.


3. Divide the total weight of the vehicle by the engine's horsepower to calculate the engine's horsepower-to-weight ratio. For instance, if a 2,800-lb. vehicle produces 300 horsepower, the power-to-weight ratio is 1 horsepower for every 9.33 lbs. To calculate the engine's torque-to-weight ratio, simply substitute the horsepower figure with the torque figure.
