Question

In the sand slinger machine, the density of sand is a result of its ___________

(a) Inertia

(b) Acceleration

(c) Velocity

(d) Mass

I got this question in an interview.

Question is taken from Moulding Machines topic in portion Moulding Machines & Special Moulding Processes of Foundry and Forging

Answer 1

Correct answer is (a) Inertia

For explanation: While the sand is rammed in the molding boxes using a sand slinger, sand is filled and rammed at the same time. The density of sand is the result of sand’s inertia which is uniform throughout the mould.
