Static torque is basically an applied force, but applied about a centre instead of in a straight line. Dynamic torque, such as that produced by an engine, is a force translated from a straight line (piston) to a circular path (crank) and since its a force at a velocity, its rated as power.
Fundamentally: power = torque x rpm Power and torque both make noise, but they are different in how they are measured and what they mean. Torque is not related to time. Power is a time-related rate. Most engineers talk about torque when they need to understand how much force is applied from a dead stop. It is force X radial distance. Huge torque may have very little power (in HP or Watts) behind it. Imagine a really strong guy with a really long wrench unfastening a bolt. He can develop lots of torque, but ultimately he can put out very little power (about 1/4 HP or 185 W for humans) over an extended time.
Torque is the cars power, horsepower is only the rate at which the torque is produced.
Torque is the cross product of radius and force .Torque is a twisting effect. Torque is the cross product of radius and force .Torque is a twisting effect.
Power is the time rate of change of energy, dE/dt= power= Force x velocity=Fv.
by all having the ability to do work, but some may have the ability to do more or less than energy
A dynamometer is used to measure force, torque or power of a engine. A dynamometer also can measure the torque and power needed to power a given driven machine.
it intial power is low and did not produce much energy
Engine power is rated in horsepower and in torque. In simple terms torque is the power that gets things moving and horsepower is the force that keeps things moving.
In physics terms, work is a force acting through a distance, energy is in the same units as work, and power is work per unit of time.
Energy is related to power in that power is energy per second. The units for power are J/s, otherwise known as a Watt (W).
im not entirely sure, but id assume it would be to build up torque so it can accelerate faster, this is common with most automatic cars, torque is the force of rotation, like push is the force of movement away from the energy source, torque is how many kg/cm2 the engine can create, creating more power and acceleration
from power= torque*angular speed u can calculate torque and from torque u can find the force if the radius is known.
Yes, weight is a measurement and torque is power. (just think kinetic energy)
at starting or initial stage there is no acceleration,it requires more force or power to move any body during initial stage,where as in running condition,it also requires some force or power whioch is less then the imitial power.hence the starting torque is always > pull up torque
A dynamometer measures force, torque, and power. It can be used to measure the power of an engine.
force times length is the dimension for Work or Energy or Torque. Some examples are Newton meters (equivalent to Joules), inch pounds, foot pounds. The pounds are pounds force, not pounds mass.
To explain this in simple terms, when the spark plug fires, it burns the gas/air mixture. This causes an explosion. The explosion forces the piston down. This forcing the piston down causes the crankshaft, which the piston is connected to, to turn. The turning of the crankshaft creates a turning force. This force or energy is sent to the transmission by way of the torque converter. This torque converter takes this turning power and turns into energy the tranmission can use. In turn the tranmission does its job and it turns the axis. This is what causes the wheels to turn. So the torque itself is created by the downward force of the pistons.
Power is energy expended in a given time.
energy = power x time
Assuming you are referring to mechanical energy:Work or energy (work can be thought of as a transfer of energy) is force x distance. Power is energy / time. Thus, power is force x distance / time Which is equivalent to: power is force x speed
Pounds is another measure of force, e.g 14.7 pounds per square inch. "Newton meter" is a measure of Energy, Newton is the measure of force. Ft-pound is a measure of energy e.g 3/4 ft-pound =1 Newton meter. This gives Newton = 9/40 Pound = .225 Pound . Torque is the most commonly used application for Newton.metre (Nm) Pounds per square inch is a unit of Pressure ,which has nothing to do with Energy or Torque. Torque is a rotational form of energy. The maximum Torque of a motor of any type is usually specified by the manufacturer. Incidentally, Torque measured in Nm is NOT the same thing as Power. Power is measured in Kilowatt (Kw) or in Watts if it is a very low power motor. We are discussing Engineering terms here, and we need to be sure we understand what we are discussing, and use the correct terms to avoid confusion.
Power is express at force, or energy, or strength
Power is the time derivative of Energy, P=dE/dt.
Many bits of data relate to an engine's rating.Efficiency (energy in to energy out); power output; torque (the strength of the turning force); weight to power comparison; and so on.
