Answer both parts
The laboratory mechanism used to test the fatigue life of materials is
Select one
a. A rotating shaft with an applied torsion load
b. NONE
c. A rotating shaft with an applied axial load
d. A rotating shaft with an applied bending load
e. A rotating shaft with an applied combined load
In tensile test the percentage of
elongation was 29.8%. If the final
length reached to 84.37mm, so the
gauge length is:
65mm
O 62mm
O 72mm
78mm

At operating stress of 360MPa, the number of cycles to fail the specimen is 390 cycles, and at operating stress of 130MPa, the number of cycles to fail the specimen is 11,900 cycles. A test sequence as follows is designed: first, operating stress of 420MPa for 7 cycles, second, operating stress of 360MPa for 65 cycles, and third, operating stress of 130MPa for 325 cycles. Determine at what number of cycle and which operating stress level the specimen would be expected to fail if the above sequence is repeated.arrow_forwardif the tensile test is broken outside the gauge length, what does that refer to?
