Why is it necessary to measure force in a modal test .
Step by step
Solved in 2 steps
- What information does a hardness test reveal?why do we physically mark gauge length on the samples before the test even though the machine is measuring displacement for us.(Tensile Testing Machine) What is the effect of rate of loading, what is a soft start what is its importance?For what purpose is A uniaxial tensile test performed?
- what is the Rockwell hardness testHardness tests are performed more frequently than any other mechanical test for several reasons: (Choose all that apply): Other mechanical properties can be estimated from hardness data such as tensile strength The test is simple and inexpensive The test is nondestructive, which means that the specimen is neither fractured or excessively deformed after the test Testing apparatus is relatively expensivePls help ASAP
