4.4 mm

3.5 mm

5.1 mm

6.45 mm

Solution:

The working temperature of cold working is below a certain temperature. What is this temperature called?

Critical temperature

Recrystallization temperature

Transition temperature

Solution:

If the minimum bend radius of a material is small, this indicates that the material is...

Likely to crack easily when bent

Highly brittle in nature

Will have high tensile strength

Highly ductile in nature

Solution:

What is the correct statement about the projected area in orbital forging compared to the original projected area of the workpiece?

The projected area for pressing is equal to the original projected area of the workpiece.

The projected area for pressing is less than the original projected area of the workpiece.

The projected area for pressing is zero, but the original projected area of the workpiece is not zero.

None of the above.

Solution:

Which of the following statements about metal forming operations is false?

In blanking operation, the metal workpiece is removed from the primary metal strip or sheet when it is punched. In this case, the removed part is the final product.

None of the above

In shearing operation, the unwanted material is trimmed and removed from sheet metal. In this case, the shearing force is used to cut the sheet metal into 2 parts.

In bending operation, the metal is deformed when we apply a force on the metal, which will bend it at an angle and form the desired shape.
