Find the moment reaction at point A (Ma), generated by forces of P1 = 1200N, P2 = 900N and P3 = 1950N that are actuating on beam, the beam has two horizontal distances d1 =3.0m and d3 = 4.0m the distance d2 = 3,1m is inclined according to the angle 30° Note: Positive movements must be cosidered as clockwise

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

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.
