Question:
Cracks appear in weld and base metal when the localized stresses exceed the ——––––––––– strength of a metal.
Cracks appear in weld and base metal when the localized stresses exceed the ——––––––––– strength of a metal.
Show Hint
Always design welds with adequate strength to avoid exceeding the yield strength of the material, which can cause cracks under stress.

The Correct Option is D
Solution and Explanation
When localized stresses exceed the yield strength of a material, plastic deformation occurs, potentially leading to cracks. In welding and metalworking, controlling these stresses is critical to preventing defects in the weld and base metal.

- An intermediate shaft of a gearbox, supporting two spur gears A and B and mounted between two bearings C1 and C2, is shown in the below figure. The pitch circle diameters of gears A and B are 500 and 250 mm respectively. The shaft is made of alloy steel 20MnCr5. (\( S_{ut} = 620 \) and \( S_{yt} = 480 \) N/mm\(^2\)). The factors \( k_b \) and \( k_t \) of the ASME code are 2 and 1.5 respectively. The gears are keyed to the shaft. Determine the shaft diameter using the ASME code.
