Suppose that the prime factorizations of two positive integers x and y are expressed using a common set of primes as follows:

x = p1? 1·p2? 2? pn? n
y = p1? 1·p2? 2? pn? n

(a) what is the prime factorization for x · y?
(b) suppose y | x. what is the prime factorization for x / y? (it is fine to have some prime factors raised to the zero power in your answer.)

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
