Enter the maximum stress (N/m^2) and the total surface area (m^2) into the Maximum Mass Calculator. The calculator will evaluate and display the Maximum Mass. 

Maximum Mass Formula

The following formula is used to calculate the Maximum Mass. 

Mmax = S * A / 9.81

  • Where Mmax is the Maximum Mass (kg)
  • S is the maximum stress (N/m^2) 
  • A is the total surface area (m^2) 

How to Calculate Maximum Mass?

The following example problems outline how to calculate Maximum Mass.

Example Problem #1:

  1. First, determine the maximum stress (N/m^2). 
    • The maximum stress (N/m^2) is given as: 425.
  2. Next, determine the total surface area (m^2). 
    • The total surface area (m^2) is provided as: 30.
  3. Finally, calculate the Maximum Mass using the equation above: 

Mmax = S * A / 9.81

The values given above are inserted into the equation below and the solution is calculated:

Mmax = 425 * 30 / 9.81 = 1299.69 (kg)


Example Problem #2: 

For this problem, the variables needed are provided below:

maximum stress (N/m^2) = 785

total surface area (m^2) = 65

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer. 

Mmax = S * A / 9.81 = ?
