Power knowledge
Horsepower was originally formulated by the French and Germans, but since the horse they measure is a smaller horse than the average horse, with a 50-horsepower engine, it is impossible to imagine a 50-horsepower engine. Driving on a motorcycle, 35 horses should be imagined as appropriate. The use of (ps) to represent the unit of horsepower was the first symbol used by the Germans, and it has been used until now.
What is 1 horsepower? 1 horsepower is the force that lifts an object weighing 75 kilograms (kg) by 1 meter (m) in 1 second, which is called 1 horsepower. In the daily specification table, such as: 70ps/8000 rpm , which means that the engine can produce 70 horsepower at 8000 revolutions per minute.
rpm is an abbreviation for engine revolutions per minute.
What is torque? Torque, also known as torque, is the moment that makes the shaft rotate. The common unit of torque in XXX is kg-m (SI unit is Nm).
In order to better understand the concept of torque, here are a few examples. For example: use a screwdriver or wrench to tighten a screw. If the length of the screwdriver or wrench is 1m, add a force of 1kg to one end of the screwdriver or wrench, then the tightening torque of the screw is 1kg-m. If the length of the screwdriver or wrench is 0.5m, in order to obtain a torque of 1kg-m, a force of 2kg must be applied. The reverse is also true, if the driving torque is the same, the further away from the center of rotation, the less force is generated.
