Quoting the auto math handbook (HP Books)
Drive wheel torque = flywheel torque x gear box ratio x diff ratio x transmission efficiency (around 0.85)
Wheel thrust is the thrust a tyre applys to the road.
Wheel thrust = drive wheel torque / wheel rolling radius
This can then gives a G'force value and g force we all agree increases with an increased rate of acceleration.
G force = wheel thrust/vehicle weight
Notice how in all these calcs for acceleration there is no mention of bhp.
From none of the above can you derive acceleration !!!!!!!!
The following definitions are universally accepted in engineering
FORCE - a simple push/pull by direct contact or by no direct contact (magnetism,gravity) and is STATIC
WORK - in mechanics is the product of FORCE x DISTANCE and expressed by force and distance (lb/ft, Newton/metres) and is STATIC
TORQUE - is the measure of a FORCE to rotate a body about an axis, expressed as lb/ft, Newton/metres and is STATIC
POWER - in mechanics is the product of FORCE x DISTANCE divided by TIME.
It is the measure of the amount of WORK in a given TIME.
VELOCITY - is the
time-rate of change in distance MPH,KPH, ft/sec
ACCELERATION -
is the time-rate of change of velocity and expressed in ft/sec/sec, mtrs/sec/sec, or as a percentage of gravity G's
FORCE, WORK and TORQUE are STATIC values.
POWER, VELOCITY and ACCELERATION are the application of the STATIC values in a given TIME.
