Question

Помогите решить задачу 1)На площадь 100см² действует сила 50НОпределите давление,оказываемое этой силы.2)Трактор ДТ-75М массой 6610 кг. имеет опорную площадь обеих гусениц 1,4см².Какое давление оказывает трактор на почву?

Answer 1

1) р=F/S=50/0,01=5000 Па (т.к. 100см2=0,01м2)

1) Fтяж=gm=10*6610=66100 H
2) 1,4см2=0,00014
3) p=F/S=66100/0,00014=472142857,143 Па

Ответ: p=472142857 Па

Ты уверена, что площадь дана в см2, а не в м2? тогда ответ красивее получится

Answer 2

Calculating Pressure

To calculate the pressure exerted by a force, we can use the formula:

Pressure = Force / Area

Let's calculate the pressure for each of the given scenarios.

1) Pressure Exerted by a Force on a 100 cm² Area: - Force: 50 N - Area: 100 cm²

Using the formula, we can calculate the pressure: Pressure = 50 N / 100 cm²

The pressure exerted by this force on a 100 cm² area is 0.5 N/cm².

2) Pressure Exerted by a Tractor with a Mass of 6610 kg on the Ground: - Mass of the tractor: 6610 kg - Area of both tracks: 1.4 cm²

To calculate the pressure exerted by the tractor on the ground, we can use the formula: Pressure = Force / Area

The force exerted by the tractor on the ground is its weight, which can be calculated using the formula: Force = Mass * Acceleration due to gravity

The acceleration due to gravity is approximately 9.81 m/s².

First, let's convert the area from cm² to m²: 1.4 cm² = 0.00014 m²

Now, we can calculate the force exerted by the tractor: Force = 6610 kg * 9.81 m/s²

Then, we can calculate the pressure: Pressure = Force / Area

After calculating, we find that the pressure exerted by the tractor on the ground is approximately 47,357,142.86 N/m² or 47,357,142.86 Pa.

These calculations demonstrate the pressure exerted by the given forces in the provided scenarios.
