Can a force produce a torque when there is no lever arm?
no because to get a torque you must multiply lever arm by force. If lever is zero, then torque is zero
How do you Convert Torque Nm to Force N?
Torque T=Nmsin x, thus Force N=T/msin x. If sin x is zero Torque is zero and Force is zero.
When torque has no net torque what is it called?
In that case, you can say that:* The net torque is zero, or equivalently that * The sum (vector sum, to be precise) of all the torques is zero.
What is An example of case when resultant force is zero but torque is not zero?
[object Object]
Give an example of a case when the resultant force is zero but resultant torque is not zero?
A couple.
Is there any torque if force is zero?
NO. not at all b/c torque is directly related to force
How will an object move if it is acted on by a positive net torque and force of zero?
A torque will make it rotate - or change its rotation.
If the torque of the rotational motion be zero then the constant quantity will be?
angular momentum
Why torque is zero when force is applied to point that passes through pivot point?
Torque is defined as the product of the distance from the pivot point, times a force, times an angle function. If any of the three factors is zero, the product is zero. In this case, the distance from the pivot point.
Performance curve of a single phase induction motor?
The performance curve can be a graph of torque versus speed. The torque is zero at zero speed and also at the synchronous speed. Normally an induction motor operates at 90-97% of the synchronous speed, where the slip is between 10% and 3%. In this region the torque is proportional to the slip. As the torque is increased the speed falls until the motor stalls and the speed drops to zero. Below the stalling speed the torque rises between zero speed and the stalling speed. Because the torque is 0 at 0, a single-phase induction motor needs a separate starting winding fed by a starting capacitor to produce a little positive torque that starts the motor.
A planet revole around the sun under the affect of gravitation exerted by the sun why the torque on the planet due to gravitation force is zero?
Because torque is (magnitude of the force) x (distance between the point where the force is applied and the center of rotation). Gravitational force is always directed toward the center of rotation, so the second factor is zero, and the torque is therefore zero.
How do you calculate the output torque and speed when s equals 0?
Multiply by zero.
