A. It increases with depth in a fluid of constant density.B. At a point it acts equally in all directions.C. It is independent of fluid density.D. Its resultant on a plane surface acts at the centre of pressure.
A. A pin support can provide two force reactions in a plane.B. A roller support provides one reaction normal to its surface.C. The bending moment at an ideal simple support is zero.D. Both supports always resist a couple moment.
Correct Answer: A|B|C
Explanation:
Ideal pin and roller supports do not resist moments.
