Depending upon the output torque required, this pull eventually can match the input speed, giving a 100% lockup.
Its most widely known use is on the differential analyzer, where it was used to increase the output torque of the otherwise limited ball-and-disk integrator.
Power is delivered to the two-bladed wooden propeller though a reverse-turning gear box to reduce output net torque felt by the pilot.
Instead, if a spacecraft requires large output torque per available input power, single-gimbal CMGs are a better choice.
Intrinsic metal gear boxes allow a relatively large output torque from a small package.
Consider a mechanism such as a gear train that operates so that an input torque generates an output torque.
During testing, the output torque and rotational speed were measured to determine the brake horsepower.
However, due to friction and other inefficiencies in the mechanism, the output torque is slightly lower than the theoretical output.
This action causes a substantial increase in the mass of fluid being directed to the turbine, producing an increase in output torque.
A fluid coupling cannot develop output torque when the input and output angular velocities are identical.
