Factor of Safety given Ultimate Stress and Working Stress Solution

STEP 0: Pre-Calculation Summary

Formula Used

Factor of Safety = Fracture Stress/Working Stress
F_s = f_s/W_s
This formula uses 3 Variables

Variables Used

Factor of Safety - The Factor of Safety is ratio of ultimate state to allowable state.
Fracture Stress - (Measured in Pascal) - The fracture stress is the ultimate stress which the material can bear.
Working Stress - (Measured in Pascal) - Working Stress is the stress applied to the material.

STEP 1: Convert Input(s) to Base Unit

Fracture Stress: 40 Pascal --> 40 Pascal No Conversion Required
Working Stress: 19 Pascal --> 19 Pascal No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F_s = f_s/W_s --> 40/19

Evaluating ... ...

F_s = 2.10526315789474

STEP 3: Convert Result to Output's Unit

2.10526315789474 --> No Conversion Required

FINAL ANSWER

2.10526315789474 ≈ 2.105263 <-- Factor of Safety

Diameter of Shaft given Permissible Value of Maximum Principle Stress

Go Diameter of Shaft from MPST = (16/(pi*Maximum Principle Stress in Shaft)*(Bending Moment in Shaft+sqrt(Bending Moment in Shaft^2+Torsional Moment in Shaft^2)))^(1/3)

Permissible Value of Maximum Principle Stress

Go Maximum Principle Stress in Shaft = 16/(pi*Diameter of Shaft from MPST^3)*(Bending Moment in Shaft+sqrt(Bending Moment in Shaft^2+Torsional Moment in Shaft^2))

Permissible Value of Maximum Principle Stress using Factor of Safety

Go Maximum Principle Stress in Shaft = Yield Strength in Shaft from MPST/Factor of Safety of Shaft

Factor of Safety given Permissible Value of Maximum Principle Stress

Go Factor of Safety of Shaft = Yield Strength in Shaft from MPST/Maximum Principle Stress in Shaft

Factor of Safety given Ultimate Stress and Working Stress Formula

Factor of Safety = Fracture Stress/Working Stress
F_s = f_s/W_s
