Let me explain with an example.
Yahoo has a website. We know that million of people are going to access this site every day. In fact thousands will be clicking this website at same movement of time.
But Yahoo has limited hardware capability. Now they want to know how many people can access their website (hitting their servers) at the same time.
1. Load testing - is expected rate is matched? Yahoo estimated that a maximum of 90,000 people (example) can hit at any point of time. So load testing is performed that whether with 90,000 virtual users system is performing well or not?
2. Stress testing - if we slowly increase users from 90,000 to say 91,000 then to 92,000 then to 93,000 and so on...then at what time servers crash or site stopped responding?
3. Performance testing - Suppose with one user yahoo page opens in 1 sec. Then with 1000 users is it opening in 1 sec? then with 50,000 users hitting website at same time, is it opening in 1 sec....so what is performance of website up to a desired level? (up to 90,000 in this example)
*************
Above are good differences. I got clear 10 differences between load and stress testing with example

C8 stress
External is out side emotional is in
brittle materials get break when subjected to stress but malleable do not.
Normal stress and shear stress
Difference in strength, 275 and 355 refer to minimum yield stress of the material (275 MPa and 355 MPa).
Here are 15 software testing interview questions: What is software testing? What is the difference between functional and non-functional testing? What is the difference between manual and automated testing? What are the different types of testing? What is a test case? What is regression testing? What is the difference between black-box and white-box testing? What is the V-Model of software testing? What is exploratory testing? What is smoke testing? What is the difference between severity and priority of a bug? What is the purpose of test automation? What is the defect life cycle? What is the difference between Load Testing, Stress Testing, and Performance Testing? What is the role of a Test Manager in a testing team?
Stress testing means increasing the load ,and cheking the performance at each level. Load testing means at a time giving more load by the expectation and checking the performance at that leval. Volume testing means first we have to apply initial load,then at certain time increase the load and check the performance.
the differences between intonation and stress is the difference . ! :D :D hahahahahaa
The statement "Moderate levels of stress can enhance performance, but high levels of stress can impair performance" is true. This is known as the Yerkes-Dodson law, which suggests that there is an optimal level of stress that can lead to peak performance before performance begins to decline with increasing stress levels.
C8 stress
Performance testing measures Tableau dashboard load times, query execution speeds, and responsiveness. Tableau’s built-in performance recorder provides insights, but it does not automate stress testing. Datagaps DataOps Suite simulates multiple users, monitors response times, and provides optimization recommendations.
It is testing of "how" the system works. Non functional testing may be performed at all test levels. The term non-functional testing describes the tests required to measure characteristics of systems and software that can be quantified on a varying scale, such as response times for performance testing. Types of Non-functional testing are performance testing, load testing, stress testing, usability testing, maintainability testing, reliability testing and portability testing.
Yield stress is the point at which a material begins to deform permanently, while ultimate stress is the maximum stress a material can withstand before breaking. Yield stress indicates the material's ability to return to its original shape after being stressed, while ultimate stress shows its breaking point.
Stress is a bodies response and conflict is a disagreement.
