Question

Чему равна мощность, развиваемого трактором при скорости 9.65 км/ч и тяговом усилии 15кН?

Answer 1

9,65 км/ч = 2.68 м/с

тогда мощность Р=Fv=15000 H*2,68 м/с=40200 Вт = 40,2 кВт

Answer 2

Calculation of Power Developed by the Tractor

To calculate the power developed by the tractor, we can use the formula:

Power (P) = Force (F) × Velocity (V)

Given: - Velocity (V) = 9.65 km/h = 9.65 km/h × (1000 m/1 km) × (1 h/3600 s) = 2.68 m/s - Force (F) = 15 kN = 15,000 N

Using the formula, we can calculate the power developed by the tractor:

Power (P) = Force (F) × Velocity (V) = 15,000 N × 2.68 m/s

Calculating the above expression, we find that the power developed by the tractor is approximately 40,200 Watts.

Please note that the above calculation assumes that the force and velocity values provided are accurate and that no other factors significantly affect the power output of the tractor.
