Solution:

What is the purpose of extending the runner in a casting process?

to supplement the liquid shrinkage

to remove slag and dross from the material.

to allow permeability

for faster cooling rate

Solution:

Solution:

Consider a spherical casting with the following data:

Time of solidification = 1078 seconds

Diameter of spherical casting = 200 mm

Calculate the value of the solidification factor constant (in s/m²).

970,000

520,000

450,000

870,000

Solution:

Assertion (A): Converging passage is used for feeding liquid metal into a mould.
Reason (R): Inhalation of air promotes blow holes in casting.

Both (A) and (R) are true and (R) is the correct reason for (A)

Both (A) and (R) are true but (R) is NOT the correct reason for (A)

Both (A) and (R) are false

(A) is false but (R) is true

Solution:

In Glass Fiber Reinforced Plastic (GFRP) composites with long fibers, the role of the matrix is to:

Support and transfer the stresses to the fibers, reduce the propagation of cracks, and carry the entire load

Reduce the propagation of cracks, carry the entire load, and protect the fibers against damage

Support and transfer the stresses to the fibers, reduce the propagation of cracks, and protect the fibers against damage
