How do you measure the force of a Stirling engine?

SUMMARY

The force of a Stirling engine is not typically measured directly, as it varies with time and load conditions. Instead, torque and energy output are the primary metrics used to evaluate performance. The efficiency of the engine can be assessed by measuring how effectively it moves a load. While Stirling engines, such as NASA's Mod II, have potential applications in automotive power, the relationship between temperature differentials and horsepower generation requires further exploration.

PREREQUISITES
  • Understanding of Stirling engine mechanics
  • Knowledge of torque measurement techniques
  • Familiarity with energy efficiency concepts

I was wondering how the force of a Stirling engine was measured? I mean, for every degree Celsius that the temperatures differ. how much more force (or horse power) is the engine generating? Are there any other variables to this? What I'm getting is can Stirling engines power cars if enough heat is given? I've seen NASA's Mod II, but there isn't a whole lot of information.

Welcome to PF;
You would not normally measure the force since that will vary with time and depend on how the engine is driving the load.
You could measure the torque, or the energy, (and the efficiency) - you do this by getting it to move a load around.
