What generates heat when the motor is running?
The frictional losses and the resistive losses generate heat in a motor
What oil used in hydraulic bending machine?
to reduce frictional losses and increase lubrication
What is windage loss of motor?
Windage loss is essentially frictional losses acting on rotating members due to air resistance.
Which loss is not common between a transformer and rotating machines?
Frictional , rotating losses are not common to transformers and rotating machines. these are specific to rotating machines.
What is a static force?
A static force is a frictional force between two forces!
What generates heat when the motor is running?
The frictional losses and the resistive losses generate heat in a motor
What oil used in hydraulic bending machine?
to reduce frictional losses and increase lubrication
What is the losses of three phase induction motors?
Iron Loss Copper Loss Frictional loss
Why cant a machine be one hundred percent affective?
The reason why amachine cant be one hundred percent effective is as a result of losses.For Electrical machine such as alternator we have Mechanical losses(such as windage and frictional losses)and Electrical losses(such as copper loss in the rotor winding and stator winding).In Mechanical machine the main losses are windage and frictional losses.NOTE;ALL THIS LOSSES RESULT IN THE PRODUCTION OF HEAT,THUS REDUCING THE EFFICIENCY OF THE MACHINE.
How does the amount of work the screwdriver does on the can compare with the amout of work you do on the screwdriver?
A screwdriver should be 100% efficient, if there are any small losses they will be due to deforming the screwhead, or frictional losses on the screwhead.
What affects RPMs?
Friction affects the RPM of a vehicle. Frictional losses in the engine result in a restriction in revolutions per minute.
Why torque is not zero in no-load speed?
Because even on no load the motor has frictional losses in the bearings and windage around the rotor.
What is windage loss of motor?
Windage loss is essentially frictional losses acting on rotating members due to air resistance.
Which loss is not common between a transformer and rotating machines?
Frictional , rotating losses are not common to transformers and rotating machines. these are specific to rotating machines.
When a toy truck collides into a toy carthe momentum of what is the same before and after the collision?
The sum of the momentum of the two toys before the collision will be the same as the momentum of the two toys after the collision except for some losses due to heat dissipation and frictional losses.
2 kinds of forces?
Frictional force and non frictional
When was Frictional Games created?
Frictional Games was created in 2006.
