8.30 Ifa component fabricated from an S-590 alloy (Figure 8.30) is to be exposed to a tensile stress of300 MPa (43,500 psi) at 650°C (1200°F), estima te its rupture lifetime.

The failure stress of a homogeneous steel bar having a diameter of 10 mm is 250 MPa. Using a factor of safety of 2.0, calculate the maximum load in N that the bar can support.

PROBLEM 3-18 GIVEN: A tension test was performed on a magnesium alloy specimen having a diameter 0.5 in. and gage length of 2 in. The resulting stress-strain diagram is shown in the figure. or (ksi) 4(0) 25 15 0.008 REQUIRED: If the specimen is stressed to 30 ksi and unloaded, determine the permanent elongation of the specimen.

(b) (i) A tensile test specimen made from 0.4% C steel has a circular cross section of diameter d mm and a gauge length of 25 mm. When a load of 4500 N is applied during the test, the gauge length of the specimen extends to 25.02 mm.

i need the answer quickly

1. Titanium alloy with an elastic modulus of 107 GPa (15.5 x 106 psi) and an initial diameter of 3.8 mm (0.15 in. ), only elastic deformation occurs. If the maximum permissible elongation is 0.42 mm, find the specimen's maximum length before deformation (0.0165 in.) 2.) With a load of 89,000 N (20,000 lbf), a steel bar 100 mm (4.0 in.) long with a square cross section 20 mm (0.8 in.) on one edge is pulled in tension and undergoes an elongation of 0.10 mm (4.0 103 in.). Calculate the steel's elastic modulus, assuming the deformation is fully elastic. Please indicate the given sir. Thanks alot…

#4 will upvote to anyone who will answer

A specimen of metal of original length 80mm and original diameter 21mm was subjected to tensile a test. The load and extension at the limit of proportionality were found to be 105,000N and 0.082mm. The yield point was at a load of 112,00ON. The maximum load before the material failed was 199,000N. The final length at failure was 91mm. Calculate: i. the stress at the limit of proportionality i. the yield stress iii. the ultimate tensile stress iv. the value of Young's Modulus V. the strain at failure
