Shaft Generator Calculation Formulas
These formulas are used to solve either a shaft (with one or more sections) or a beam (with one constant section) with multiple supports and loads.
The shaft/beam axis is aligned with the Z axis. If the impact of the material density is included in the calculation, the gravity vector is aligned with the Y axis.
|E||modulus of elasticity in tension|
|J||moment of inertia|
|G||modulus of rigidity|
|b||shear displacement ratio|
|a||a = 3 for HMH|
|a = 4 for Tresca-Guest|
Modulus of elasticity E = 210 000 MPa
