A new high- temperautre alloy is to be used for a 3-mm diameter tensile support member for an impact-sensistive instrument weighing 900 N. The instrument and its support are to be enclosed in a test vessel for 3000 hours at 871 deg C. A laboratory test on the new alloy used a 3-mm diameter specimen loaded by a 900 N weight. The specimen failed due to stress rupture after 100 hours at 982 deg C. Based on the test results, determine whether the tensile support is adequate for the application.
