A component is subject to cyclic loading, experiencing a maximum stress of 100 MPa. The frequency of the cyclic load is 2 Hz, and the component operates 6 hours per day. The material's S-N curve is described by the equation \(\sigma = 4000N^{-0.13}\).

Determine after how many days a crack would initiate.

The number of days before a crack initiates in a component subjected to cyclic loading can be determined by applying the S-N (Stress-Number) curve of the material.

This curve provides a relationship between stress levels and the number of loading cycles before failure. To find the number of cycles before failure, we plug the maximum stress (σ = 100 MPa) into the material's S-N curve equation given as σ = 4000N^-0.13. Solving for N gives the number of cycles before failure. Given the frequency of the cyclic load (2 Hz) and operation time (6 hours per day), we can calculate the number of cycles that occur each day. Dividing the total number of cycles before failure by the number of cycles per day gives the number of days before a crack initiates.
