A math problem:
Electric motor A produces 700 ft lb of torque at 2500 rpm and is hooked directly to a hydraulic pump via a rigid coupling.
Electric motor B produces 350 ft lb of torque at 5000 rpm and is mounted to a 2:1 reduction gearbox. The output shaft of the gearbox is hooked to a hydraulic pump via a rigid coupling.
Which ELECTRIC motor delivers more torque to the input shaft of the pump. Which pump delivers more Power to the input shaft of the pump. Assume no losses from the couplings or reducer.
The snaggle toothed diesel guys can't admit to facts so they go back to chest pounding to make their argument. :B
Diesel, gas, electric, steam... It's all horsepower. Speaking of steam, that's chugging a long. Why do diesels have to scream at 2000-3000rpm to pull a grade? How can you possibly relax with your engines running at speeds that are a blur to the naked eye? Gives me a migraine just thinking about it.;)
