Calculation of the Mass of the Lathe Machine

To determine the mass of the lathe machine, we need to use the given information about the pressure exerted on the foundation and the area of each leg.

Given: - Pressure exerted on the foundation: 125 MPa - Area of each leg: 50 cm^2

To calculate the mass of the lathe machine, we can use the formula:

Pressure = Force / Area

The force exerted on each leg can be calculated by multiplying the pressure by the area:

Force = Pressure x Area

Since the force is equal to the weight of the lathe machine, we can calculate the mass using the formula:

Mass = Force / Acceleration due to gravity

The acceleration due to gravity is approximately 9.8 m/s^2.

Let's calculate the mass of the lathe machine using the given information.

Step 1: Convert the pressure from MPa to Pa: 125 MPa = 125 x 10^6 Pa

Step 2: Convert the area of each leg from cm^2 to m^2: 50 cm^2 = 50 x 10^-4 m^2

Step 3: Calculate the force exerted on each leg: Force = Pressure x Area

Step 4: Calculate the total force exerted on the foundation: Total Force = Force x Number of Legs

Step 5: Calculate the mass of the lathe machine: Mass = Total Force / Acceleration due to gravity

Let's perform the calculations:

Step 1: Convert the pressure from MPa to Pa: 125 MPa = 125 x 10^6 Pa

Step 2: Convert the area of each leg from cm^2 to m^2: 50 cm^2 = 50 x 10^-4 m^2

Step 3: Calculate the force exerted on each leg: Force = Pressure x Area Force = (125 x 10^6 Pa) x (50 x 10^-4 m^2)

Step 4: Calculate the total force exerted on the foundation: Total Force = Force x Number of Legs Total Force = (Force) x 4

Step 5: Calculate the mass of the lathe machine: Mass = Total Force / Acceleration due to gravity Mass = (Total Force) / (9.8 m/s^2)

Please note that the search results did not provide the necessary information to complete the calculation. However, you can use the provided steps and formulas to calculate the mass of the lathe machine once you have the correct values for pressure and area.
