generally rating means the condition when the machine can give maximum efficiency without being overheated .In Transformers and generators it is decided by core as well as copper loss(flux proportional to supply voltage,current proportional to copper loss).so both are rated in kVA whereas motors are rated as maximum output they can deliver i.e kW.
Welding is done with a high current and low voltage. The voltage of a 500 amp welder might be 10 v so the power rating in that case would be 5000 watts.
what is the power rating of a transister
Maximum power rating describes the maximum power at which a device can operate without reaching an excessive temperature. For example, in the case of a resistor, if its maximum power rating is exceeded, then it may burn out.
Check the nameplate rating on the door or door frame of your washer, it should tell you the amp rating or the kw rating of the machine. If it only has the KW rating of the machine, simply divide the KW rating by the voltage of the receptacle and it'll give you the current (ampere) rating. Typically, a modern washing machine will draw approximately 7-12 amps. However, anticipate a higher amperage when starting the machine as the machine will draw 1.5X the rated current to start the machine (starting current). Regardless of the amp rating, the NFPA-70 (National Electrical Code) requiresa 20 Amp fuse or circuit breaker; and the circuit for the washing machine must be on its own, dedicated circuit.
Knowing the power rating of a transformer will help an operator use the transformer within its design limitations with regard to heating of the windings and their insulation.
The size of a resistor is a physical characteristic that determines its power rating.
How long will it take a machine with the power rating of 60 W to 368 rules of work
We have no way of knowing what power the machine was rated for, but with the information given in the question, we can calculate the power it delivered during the crate-lift: It was (1.96) x (mass of the crate in kilograms) x (distance the crate was lifted in meters) watts.

Yes, provided the power inverter has a high enough power rating (wattage) for the CPAP device.
The power rating of the machine can be calculated using the formula: Power = Work / Time. The work done is equal to the force applied (50kg * 9.8 m/s^2) multiplied by the distance (10 meters). Therefore, the power rating can be calculated as (50kg * 9.8 m/s^2 * 10m) / 5 seconds.

Welding is done with a high current and low voltage. The voltage of a 500 amp welder might be 10 v so the power rating in that case would be 5000 watts.
Power can be defined as work done (force * distance) / time taken. Since distance / time is velocity, power could be defined as force overcome * velocity, Pedalling a 70 kg rider up a 10 degree incline, the maximum speed obtained is 8 metres per second. The force due to gravity acting against the rider is: sin 10 degrees * 70 * 9.81 = 119 newtons (approx) So force overcome * velocity = 119 * 8 = 952 watts (maximum power rating) Note: Rolling resistance has been ignored. Air resistance has also been ignored.
