Experimentally one can find the grain size as function of time. If the K value is given as 3mm/sec (temperature dependent proportionality constant) and n is 0.2. Find the grain diameter at t =2sec?

Experimentally one can find the grain size as function of time. If the K value is given as 3mm/sec (temperature dependent proportionality constant) and n is 0.2. Find the grain diameter at t =2sec? Correct Answer 3.45mm

The equation linked with the above mentioned question is given as D = Ktᶯ. Here K is the temperature dependent proportionality constant and n is a number less than 0.5. Substituting the respective values we get the D value as 3.45mm.

Consider the relational schema given below, where eId of the relation dependent is a foreign key referring to empId of the relation employee. Assume that every employee has at least one associated dependent in the dependent relation. Employee (empId, empName, empAge) Dependent(depId, eId, depName, depAge) Consider the following relational algebra query: ΠempId(employee)-ΠempId (employee⋈(empId = eID)∧(empAge ≤ depAge)dependent) The above query evaluates to the set of empIds of employees whose age is greater than that of

The largest size of immobilised segment of dislocation in a Frank Read (FR) source contained in a polycrystalline material is of the order of grain size. In a metal of 10 μm grain size, the shear stress required to operate such a FR source is 100 MPa. If the grain size in the same metal is reduced to 10 μm, the shear stress required to operate such FR source would be . . . . . . . . MPa.
