Why is torque important?
Torque is a crucial part of generating power from a car’s engine, as it represents the load an engine can handle to generate a certain amount of power to rotate the engine on its axis.
Multiply this torque force (in lb-ft.) by the axis’s rotational speed per minute (RPM) and you get the engine’s power output..
What is Torque simple words?
In simple terms, the definition of torque is the engine’s rotational force. It differs from horsepower as it refers to the amount of work an engine can exert, while horsepower defines how quickly that work can be delivered. It’s why torque is often referred to in layman’s terms as ‘pulling power’, ‘oomph’, or ‘grunt’.
Can you have negative torque?
Negative torque does not exist, just like negative force and negative energy don’t exist. (Don’t get me started on quantum mechanics) It’s an absolute value, meaning it can only be positive. The direction, however, can vary. Negative torque does not exist, just like negative force and negative energy don’t exist.
How do you calculate current torque?
Since the equation for torque on a current-carrying loop is τ=NIABsinθ τ = N I A B sin , the units of N ⋅ m must equal units of A ⋅ m2 T.
How is motor torque calculated?
Torque (lb.in) = 63,025 x Power (HP) / Speed (RPM)Power (HP) = Torque (lb.in) x Speed (RPM) / 63,025.Torque (N.m) = 9.5488 x Power (kW) / Speed (RPM)Power (kW) = Torque (N.m) x Speed (RPM) / 9.5488.
What is the maximum torque on the motor?
The developed torque is maximum when the rotor resistance per phase is equal to the rotor reactance per phase under running conditions. By putting the value of sX20 = R2 in the equation (1) we get the equation for maximum torque. The above equation shows that the maximum torque is independent of the rotor resistance.
What is Torque in physics definition?
Torque is a measure of how much a force acting on an object causes that object to rotate. The object rotates about an axis, which we will call the pivot point, and will label ‘O’. We will call the force ‘F’.
What is the max torque?
The primary use of torque is to make the car accelerate, and the number usually quoted is the maximum torque of the internal-combustion engine at the crankshaft – and that’s usually higher than the amount at the wheels. … A heavier SUV will need more torque to begin moving or keep cruising.
What is the position of the loop when the current is maximum?
What is the position of the loop when the current is maximum? The maximum current is when the loop is halfway into the region of the field. The maximum current is when the loop is at the beginning of the region of the field.
How do you find the torque of a magnetic field?
The torque on the dipole is τ = µ×B, where B is the external magnetic field. The magnitude of this torque is µB sinθ, where θ is the angle between B and µ (that’s just definition of cross-product).
What is the torque on the coil when the coil is perpendicular to the field lines?
If the plane of the coil is perpendicular to the direction of the magnetic flux, So, the perpendicular on the coil is parallel to the field. So, The torque is zero. If the plane of the coil is parallel to the direction of the magnetic flux lines, So, the perpendicular on the coil is perpendicular on the field.
How do you get maximum torque?
Note that the torque is maximum when the angle is 90 degrees. A practical way to calculate the magnitude of the torque is to first determine the lever arm and then multiply it times the applied force. The lever arm is the perpendicular distance from the axis of rotation to the line of action of the force.
How does torque affect speed?
Torque multiplied by rpm returns horsepower. Basically, the faster the crankshaft spins with the same amount of force, the more power an engine will make. A car with more hp than torque will always be quicker since this gives a car acceleration and speed.
How much torque does a human have?
An easy estimate of the force is a person’s weight in pounds (because a pound IS a unit of force). That was going to be my answer as well. If you push on a 1 mile long (5280 feet) lever arm with say… 200lbs, which is about what most adult men can bench press then you’d produce 1,056,000 ft*lbs of torque.
What is torque in magnetic field?
A magnetic field exerts a torque which tries to align the normal vector of a loop of current with the magnetic field. The size of the torque on a loop of current is torque = (# turns) * (current) * (loop area) * (mag field) * sin(theta) where theta is the angle between the magnetic field and the loop’s normal vector.
