Question
A cube is dropped into the cylinder and the water rises. The length of a side of the cube is 3.7 cm. Specific weight of water is 9.81 kN/m3.
Find the density of the cube, the specific gravity of the cube. Where is the vertical CG of the cube? Vertical center of buoyancy based on SWL?
Transcribed Image Text:### Measuring the Volume of an Object Using a Graduated Cylinder
#### Diagram Explanation
The image shows two graduated cylinders with a capacity of 250 mL each, marked with a precision of 5 mL at 20°C.
- **Left Cylinder**:
- Contains a liquid up to the 150 mL mark. This represents the initial volume of the liquid before any object is submerged.
- **Right Cylinder**:
- Contains the same liquid, but an object has been submerged, raising the liquid level to the 200 mL mark. This increase indicates the volume of the submerged object.
#### Volume Calculation
To find the volume of the object:
1. **Initial Volume of Liquid**: 150 mL
2. **Final Volume with Object**: 200 mL
3. **Volume of Object** = Final Volume - Initial Volume = 200 mL - 150 mL = 50 mL
This method is a practical application of Archimedes’ principle and is often used in laboratory settings to measure the volume of irregularly shaped objects.
