Designing a shaft for variable loads with S.N. diagram
S.N. diagram:
- S.N. diagram is a graphical representation of the relationship between stress (S) and cycles to failure (N) for a material.
- It is used to determine the fatigue strength of a material.
- The diagram consists of two curves - one for the stress level below which the material has an infinite life (endurance limit) and one for the stress level above which the material fails after a finite number of cycles.
Designing a shaft for variable loads:
- When designing a shaft for variable loads, it is important to consider the fatigue strength of the material.
- The S.N. diagram can be used to determine the fatigue strength of the material based on the stress level and the number of cycles to failure.
- The design of the shaft should be such that the stress level is below the endurance limit of the material to ensure infinite life.
Drawing the S.N. diagram:
- To draw the S.N. diagram for a material, a series of fatigue tests are conducted at different stress levels and the number of cycles to failure is recorded.
- The data is plotted on a graph with stress (S) on the y-axis and cycles to failure (N) on the x-axis.
- Two curves are drawn on the graph - one for the endurance limit and one for the stress level at which the material fails after a finite number of cycles.
Choosing the appropriate curve:
- When designing a shaft for variable loads, it is important to choose the appropriate curve on the S.N. diagram.
- If the stress level is below the endurance limit, the material will have an infinite life and the endurance limit curve should be used to determine the fatigue strength of the material.
- If the stress level is above the endurance limit, the material will fail after a finite number of cycles and the stress level curve should be used to determine the fatigue strength of the material.
Drawing the S.N. diagram for a shaft:
- When drawing the S.N. diagram for a shaft, the stress level and the number of cycles to failure are determined based on the expected load on the shaft.
- The data is plotted on a graph with stress (S) on the y-axis and cycles to failure (N) on the x-axis.
- If the stress level is below the endurance limit of the material, the endurance limit curve is used to determine the fatigue strength of the shaft.
- If the stress level is above the endurance limit, the stress level curve is used to determine the fatigue strength of the shaft.
Drawing the S.N. diagram by joining 0.9 at 1000 cycles and at cycles by a straight line on a log S-log N graph:
- When drawing the S.N. diagram for a shaft, it is common practice to use a log S-log N graph.
- This graph allows for a better visualization of the data over a wide range of stress levels and cycles to failure.
- To draw the S.N. diagram for a shaft using a log S-log N graph, the 0.9 at 1000 cycles and at cycles are joined by a straight line.
- This line represents the fatigue strength of the shaft for stress levels between the endurance limit and the stress level at which the material fails after a finite number of cycles.
