Acantilever beam is subjected to a concentrated service live load of 25.000 lb(111 kn) acting at a distance of 3 ft 6 in.(1.07m) from the wall support. its cross section is 10 in. times 20 in. with an effective depth d = 17 .(432 min). design the stirrup needed. f_c = 3000 psi (20.7 mpa), normal-weight concrete f_y = f_yt = 40,000 psi(275.8 mpa)

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.

Which of the following components of a pid controlled accumulates the error over time and responds to system error after the error has been accumulated? a)- proportional b)- derivative c)- integral d)- on/off.
