in stress testing load runner allows you to conduct stress testing on our application build to estimate stability of build under various load levels applied upto some long time.In load testing load runner allows you to apply various operations load testing under various load levels.

stress testing: for all types of applications
deny the resources it needs. like: application is developed for 256MB Ram or higher. you test on 64Mb Ram see it fails and fails safely
Load testing: for client/server applications { 2-tier or hgher }
Your reqt: 5000 users at a time. Check throughput of application, if achieved, load testing for reqd load is done. If not tune the application developed and/or servers

stress testing:The purpose of stress testing is used to find system capacity handing large no of transtions during the peak conditions.
Load testing: Testing an application,such as testing an website under range of loads to determine at what point the system degrads or fail.

Stress Testing:
Stress testing is designed to test the software with abnormal situations. Stress testing attempts to find the limits at which the system will fail through abnormal quantity or frequency of inputs. For example,Higher rates of interrupts, Test cases that require maximum memory or other resources,Test cases that cause 'thrashing' in a virtual operating system, Test cases that cause excessive 'hunting' for data on disk systems etc.
Load Testing:
The application is tested against heavy loads or inputs such as testing of web sites in order to find out at what point the web-site/application fails or at what point its performance degrades. In load testing, response time, think time, throughput, workload etc is analyzed.

load testing is used to test customer expected configuration from high to low and low to high.
stress testing is used for testing specification of system with in limit or beyond the specification of the application.

Load test: To test the application withrequired amount of load as defined in Requirements.
Stress Test : To test the application beyond the normal operational capacity. In stress test we increase the load without providing enough resource. The purpose of this test is to see, if the application fails in adecent way without corrupting the data. Also this test is done to check for Memory leak defects.
