Question

In casting experiments performed using a certain alloy and type of sand mould, it took155 sec for a cube-shaped casting to solidify. The cube was 50 mm on a side. 1) Determine the value of mould constant in Chvorinov’s rule. 2) If the same alloy and mold type were used, find the total solidification time for a cylindrical casting in which the radius is15 mm and length is 50 mm.

Answer 1

Answer:

point charge is projected along the axis of a circular ring of charge q and radius 102 m. The distance of the point charge from the centre of the ring, where the acceleration of the charged particle is maximum will beCharge q is uniformly distributed on a ring of radius r. the ring rotates about its axis of frequency of hz. what is the magnetic induction at the centerKarna as a self controdictary character
