No, the frictional losses of an induction machine are not linear. Friction losses increase with speed and are affected by factors such as temperature, lubrication, and surface finish. These losses are typically represented as a quadratic function of speed in machine modeling and analysis.
What else can I help you with?
Are the friction losses of an induction machine linear?
No, the friction losses of an induction machine are not linear. These losses are typically influenced by factors such as speed, load, and temperature, which can make the relationship between friction losses and operating conditions non-linear.
Are the friction losses of the machine linear?
Friction losses in a machine are typically non-linear. Friction force is proportional to normal force but can vary with factors like surface roughness, lubrication, temperature, and sliding velocity, causing non-linear behavior. As a result, friction losses may change unpredictably with different operating conditions.
Distinguish between theoretical mechanical advantage and actual mechanical advantage How will these compare if a machine is 100 percent efficient?
Theoretical mechanical advantage is the ratio of the input force to the output force without considering friction, while actual mechanical advantage includes frictional losses in the machine. If a machine is 100 percent efficient, there will be no frictional losses, so the theoretical and actual mechanical advantages will be the same, resulting in a 1:1 ratio of input force to output force.
Besides a reduction in friction the only way to increase the amount of work output of a machine is to the work input?
Yes, that is correct. The work output of a machine cannot exceed the work input due to the law of conservation of energy. So, aside from reducing frictional losses, increasing the work input is the only way to boost the work output of a machine.
Is the efficiency of a machine is 60 the percentage of work input used to overcome friction?
No, efficiency of a machine is a measure of how well input energy is converted into useful output work, and is calculated as useful work output divided by total work input. The percentage of work input used to overcome friction would be related to the frictional losses in the machine, not the overall efficiency.

What oil used in hydraulic bending machine?
to reduce frictional losses and increase lubrication
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.

What are the losses have an induction machines?
A three phase induction machine have the Following losses:- 1. Stator core loss 2.Stator Ohmic loss 3.Rotor core loss 4.Rotor ohmic loss 5.Friction losses 6.windage losses 7.Stray losses 8.Also it'll depends upon the types of motor as if it is a slip ring type IM then it will have sparking losses at slip contact etc etc which are very small in comparison to above losses.
