(10 pts) If the pressure at Point B is 6.75 psi, find the specific gravity of the second liquid contained in the tank. (B) (5 pts) Sketch the free body diagram for the steel block that is submerged between the two liquids in the tank. (C) (10 pts) Using the specific gravity of the second liquid in the tank (found in part A), find the ratio of distances a and b if the block of steel has a specific gravity (SG) of 7.85. s) Is the block of steel in a stable or unstable condition? Briefly explain.
