Q:

The earing defect in the rolling of the work piece is not caused by _________

A) too high speed B) low clearance between the roll and workpiece
C) blank holding D) material dependent
 
Answer & Explanation Answer: B) low clearance between the roll and workpiece

Explanation: The non-uniform clearance between the workpiece and roll does not have a direct impact on causing hearing of the workpiece, while the material property, too high speed can cause earing defect.

Q:

An angle ? in the physical element is represented by ________ on Mohr’s circle.

A) 2? B) 3?
C) 4? D) ?
 
Answer & Explanation Answer: A) 2?

Explanation: In the case of a physical element the angle between normal stress and principle stress vary from 0 to 90 degree, but in its circular representation it can vary from 0 to 180 degree. So, Mohr’s circle rotates by 2? when the physical element is rotated by ?.

Q:

The position of the neutral point in rolling does not depend upon __________

A) diameter of roll B) percentage of reduction
C) coefficient of friction D) composition of material
 
Answer & Explanation Answer: D) composition of material

Explanation: The diameter of the roll, percentage of reduction and coefficient plays a crucial role in deciding the position of neutral point along the arc of roll, but composition of material does not significantly affect the position of neutral point.

Q:

The sheet has an initial thickness of 30 mm with roll diameter of 300 mm and coefficient of friction equal to 0.2. Find the final thickness of the sample in case maximum reduction is carried out in a single pass?

A) 12 mm B) 18 mm
C) 24 mm D) 30 mm
 
Answer & Explanation Answer: B) 18 mm

Explanation: The maximum possible reduction in a single pass is equal to:
-> ?h=u² R; where u is coefficient of friction, and R is roll diameter.
-> ?h=0.22 300=12 mm
-> So, maximum possible reduction after a single pass will be equal to 12 mm
-> So, final thickness will 30-12=18 mm.

Q:

In the tube drawing and wire drawing, the nature of force applied on the material is ___________

A) compressive B) tensile
C) shear D) torsional
 
Answer & Explanation Answer: B) tensile

Explanation: The metal is drawn by pulling it out using suitable die and mandrel; hence, the nature of force is purely tensile. While the other process may have complex or compressive forces.
