Other tests use a constant load and measure the time to failure or to a critical deflection.

Even in engines operating under a constant load (such as electrical generators), turbochargers have advantages over superchargers.

The brush-setting method is satisfactory in installations in which the generator operates under a fairly constant load.

Power stations and the grid prefer to have a constant load on them to maintain the frequency and voltage.

The work parties of the mutineers brought constant new loads of ore upon their makeshift sledges.

This maintains a constant thermal load from synchrotron radiation.

Continuous black exhaust from the stack when under a constant load is also an indication that all the fuel is not being burned.

Although clamp type collars work very well under relatively constant loads, shock loads can cause the collar to shift its position on the shaft.

The valvegear driving these valves was usually simple, a single eccentric designed only to run at one speed, in one direction, for a fairly constant load.

This simple realization requires rather high voltages ( 100 V) to keep the load current constant with sufficient approximation for all practical purposes.
