Safe stress Solution

STEP 0: Pre-Calculation Summary

Formula Used

Safe Stress = Yield Strength/Factor of Safety
σ_w = σ_y/f_s
This formula uses 3 Variables

Variables Used

Safe Stress - (Measured in Pascal) - Safe Stress is based on the yield strength of the material and is defined as the yield strength divided by a factor of safety.
Yield Strength - (Measured in Pascal) - Yield strength can be defined as follows, a straight line is constructed parallel to elastic portion of stress–strain curve at strain offset of 0.002.
Factor of Safety - Factor of Safety expresses how much stronger a system is than it needs to be for an intended load.

STEP 1: Convert Input(s) to Base Unit

Yield Strength: 35 Newton per Square Millimeter --> 35000000 Pascal (Check conversion here)
Factor of Safety: 2.8 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

σ_w = σ_y/f_s --> 35000000/2.8

Evaluating ... ...

σ_w = 12500000

STEP 3: Convert Result to Output's Unit

12500000 Pascal -->12.5 Megapascal (Check conversion here)

FINAL ANSWER

12.5 Megapascal <-- Safe Stress

Safe stress Formula

LaTeX Go

Safe Stress = Yield Strength/Factor of Safety
σ_w = σ_y/f_s

Caution in using factor of safety

The choice of an appropriate value of factor of safety (N) is necessary. If N is too large, then component overdesign will result; that is, either too much material or an alloy having a higher-than-necessary strength will be used. Values normally range between 1.2 and 4.0. Selection of N will depend on a number of factors, including economics, previous experience, the accuracy with which mechanical forces and material properties may be determined, and, most important, the consequences of failure in terms of loss of life and/or property damage.
