Question

Найти площадь опоры машины если она оказывает давление 20 МПа и имеет массу 2 т​

Answer 1

Ответ:

Объяснение:

Дано:

p = 20 МПа = 20·10⁶ Па

m = 2 т = 2 000 кг

__________________

S - ?

p = F / S

p = m·g / S

S =  m·g / p = 2000·10 / 20·10⁶ = 0,001 м²

Answer 2

Calculating the Pressure Area of a Machine Base

To calculate the pressure area of a machine base, we can use the formula:

Pressure = Force / Area

Given: - Pressure = 20 MPa - Force = mass * acceleration due to gravity - Mass = 2 tons

First, let's convert the mass from tons to kilograms: 1 ton = 1000 kilograms

So, 2 tons = 2000 kilograms

Now, we can calculate the force using the formula: Force = mass * acceleration due to gravity Acceleration due to gravity, g = 9.81 m/s^2

Let's calculate the force: Force = 2000 kg * 9.81 m/s^2

Force = 19620 N

Now, we can use the formula to calculate the area: Area = Force / Pressure

Let's calculate the area: Area = 19620 N / 20 MPa

Area = 981 mm^2

So, the pressure area of the machine base is 981 mm^2.
