WebQ.2 A machine component is subjected to a Hexural stress which fluctuates between $300 MN/m^2$ and $-150MN/m^2$. Determine the value of minimum ultimate strength according to (1) Goodman relation (2) Soderberg relation. Take yield strength=0.55ultimate strength, Endurance strength=0.5ultimate strength, FOS=2. Solution: $\sigma _{max}=300N/mm^2$
Web2. Variable or fluctuating load. A variable load is a load that is applied over an area; that is, a surface. A variable load can be applied in any direction specified by a vector or can be applied normal to the surface. A function can be defined to control the magnitude of the load at different locations on the surface. 3.Impact load WebMar 13, 2024 · Get Design Against Fluctuating Load Multiple Choice Questions (MCQ Quiz) with answers and detailed solutions.
