Find a minimum two-level, multiple-output AND-OR gate circuit to realize these functions (eight gates minimum). a. f1(a, b, c, d)= Σm(10, 11,12, 15) + Σd(4,8,14)
b. f2(a, b, c, d)= Σm(0, 4,8, 9) + Σd(1,10,12)
c. f3(a, b, c, d)= Σm(4, 11,13,14, 15) + Σd(5,9,12)

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

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.
