Textbook Question
Chapter 8, Problem 10P
A large mass is supported by a piston of diameter D = 4 in: and length L = 4 in. The piston sits in a cylinder closed at the bottom, and the gap a = 0.001 in. between the cylinder wall and piston is filled with SAE 10 oil at 68°F. The piston slowly sinks due to the mass, and oil is forced out at a rate of 0.1 gpm. What is the mass (slugs)?

i. What will be the spring scale reading in newtons when the lead has been submerged to location 2?
ii. Does the spring scale reading increase, decrease, or stay the same when the cube is lowered from location
2 to location 3? Justify your answer by referencing the pressure of the fluid on the lead cube.
iii. The lead cube is lowered from above the oil's surface (location 1) to a spot just below the surface (location
2) until the cube is just above the bottom of the beaker (location 3). Describe any changes in pressure on
the bottom of the beaker during this process. Explain your answer.
