Question

⦁ A certain tractor is said to be capable of pulling with a steady force of 18kN while moving at a velocity of 8.0m/s. How much power in kilowatts and in horsepower is the tractor developing under these conditions?

Answer 1

Explanation:

Power = forces x velocity

p = 18000 x 8

p = 144000

p = 144 kilowatt

1 kw = 1.3 horsepower

144kw = 1.3 x 144 hp

= 187.2 hp
