Question

A 37-kW tractor is required to pull a 3-furrow plough with an effective width of cut of 1050 mm in clay soil. Check if the plough and tractor are matched.

Answer 1

To check if the plough and tractor are matched, we need to compare the power output of the tractor to the power requirement of the plough.

Step-by-step explanation:

To check if the plough and tractor are matched, we need to compare the power output of the tractor to the power requirement of the plough. The power requirement of the plow can be calculated using the equation:

Power = Force × velocity

To calculate the force required to pull the plough, we can use the equation:

Force = Coefficient of friction × Normal force

Since the plough is cutting through clay soil, which has a high coefficient of friction, the force required will be high. If the tractor's power output is lower than the power requirement of the plough, they are not matched.
