Result Interpretation

Sum scalar rotational inertias referred to common axis computes J_total in kg·m² using the defined engineering formula and the input values provided. J_total is expressed in kg·m². No universal acceptance threshold is defined by this calculator.

Worked Example

default_test

Given:

  • j_c = 7.0E-5
  • j_m = 0.0008
  • j_g_in = 0.00015
  • j_l_ref = 0.0012

Expected Result:

  • J_total = 0.00222

Engineering Interpretation:

Under the given input conditions, the calculated result is: J_total = 0.00222 kg·m².

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.

Formula / Method
