Practice Questions
Test your understanding with targeted questions
What does the Factor of Safety measure in design?
💡 Hint: Think about safety in engineering applications.
If a material has a yield strength of 120 MPa and the actual working stress is 60 MPa, what is the FoS?
💡 Hint: Use the formula: FoS = Material Strength / Actual Working Stress.

Challenge Problems
Push your limits with advanced challenges
A structural member is rated for 400 MPa and is subjected to an actual load of 80 MPa. Calculate its FoS and discuss if this is adequate for a construction application with occasional overloads.
💡 Hint: Focus on the ratio and implications of safety in design.
In a design project, you're unsure if the selected material can withstand the anticipated stresses. The project requires an FoS of 2. If the material has a strength of 250 MPa, what is the maximum stress you can apply?
💡 Hint: Recognize how to rearrange the FoS formula.
