Answer:
The preferred steel type for W-shapes is structural steel and the its preferred ASTM designation is ASTM A992.
Explanation:
The ASTM A992 is a structural steel and it's the most available for w-shapes; besides its availabilty, its ductility improvements makes it the preferred choice; other common designations for this shapes are ASTM A572 Grade 50,0r ASTM A36, but this designations aren't as available as ASTM A992, and it has to be confirmed prior to their specification.
Explanation:
The tear test determines the force required by a material to undergo complete failure when there is already a crack or tear present in it.
With this test we understand a material's resistance to failure when there is already a crack present.
The material which already has a crack is placed in a tensile testing or universal test machine. So, both sides of the material along the crack are pulled until material failure takes place.
