BRASS CYLINDER	VALUES
weight (N)	2.002
length (m)	0.0605
diameter (m)	0.0192
radius (m)	0.0095
volume (m3)	0.00001751

ALUMINUM CYLINDER	VALUES
weight (N)	0.621
length (m)	0.0605
diameter (m)	0.0192

Calculated Weight of water displaced by metal cylinders (F = weight of cylinder - weight of water displaced).

Water displaced by brass = 0.237N

Water displaced by aluminum = 0.135N

Calculate Theoretical apparent weight for each metal. (Apparent weight = weight of object - weight of water displaced)

Theoretical apparent weight of brass = 1.765 N

Theoretical apparent weight of aluminum = 0.486 N

1. Did the different densities of the two different metal cylinders affect the value of the buoyant force they each experienced? If it did explain why?

2. Why did the wooden cylinder float in the water while the two metal cylinders sink?
