In the given S-N cycle, there are four different samples tested for different stress values. Among given sample, the highest probability of the failure is for __________ sample.

In the given S-N cycle, there are four different samples tested for different stress values. Among given sample, the highest probability of the failure is for __________ sample. Correct Answer D

The probability of failure for a sample is determined by the stress value and number of cycles. If the stress value or the amount of cycles is high, the probability of failure is also high. So in that case, the orange curve has the highest number of cycles and stress values; hence, the likelihood of failure is highest.

Validate the statement: “For a given image in one-dimension given by function f(x, y), to sample the function we take equally spaced samples, superimposed on the function, along a horizontal line. However, the sample values still span (vertically) a continuous range of gray-level values. So, to convert the given function into a digital function, the gray-level values must be divided into various discrete levels.”
