19 Which of the following is NOT a characteristic of fluid pressure? O (A) At any point, it is equal in all directions. O (B) It acts normal to a surface. O (C) It is a shear stress. O (D) It varies linearly with depth.

Solution

19) C

Fluid pressure acts normal to the surface. And it is equal in all directions. The pressure varies linearly with the depth.

So, These three options are true except C. It\'s not a shear stress.

20) C

Ground water can not act like a surcharge load on a rigid wall. Remaining three types of loads can act like surcharge loads. So, the correct option is C.
