Well, friend, a 139cc lawn mower engine typically has around 3-5 horsepower. It may vary slightly depending on the specific make and model, but that's a good ballpark estimate. Just imagine all that power gently guiding you as you create beautiful landscapes in your yard.

This engine will have some good horsepower. It will not be as strong as like a car but it comes pretty high for a lawnmower.

1HP equals how many CC?

You can't just have a certain amount of CC's in a horsepower. Theres too many variables as Horse power is " Power from the engine " and CC is actually how much the engine is putting out. It's hard to explain but dont bother to keep trying to look for the awnser.

What is friction between moving parts of an engine?

Friction is cut down in a car engine for two very important reasons. First, cutting down friction increases horsepower. It takes horsepower to overcome friction; so anything that can be done to cut down friction will increase the horsepower. Second, friction causes heat to be produced. Too much heat is bad, because if the engine gets too hot, then metal is softened and weakened, leading to failure of engine parts. The engine has a cooling system to remove unwanted heat, but too much friction would require a larger and more efficient cooling system to remove the excess heat, which would add expense and weight to the car. Motor oil is used to cut down the friction in the car engine. Also, very close tolerances in production of engine parts helps to cut down friction.


Should others be more concerned about others than themselves?

It depends on the situation. From life saving to just lawn mowing. When life threatening first attend to yourself than other, while lawn mowing if you remind your neighbor too much about his lawn. He might just be annoyed.


Amy use 20N of force to push a lawn mower 10 meters. How much work does she do?

W = Force x Distance - - - so - - -W = 20 N x 10 m = 200 N·m = 200 Joule
