## Initialize and use
client = PhysicsClient("https://scp.intern-ai.org.cn/api/v1/mcp/20/Materials_Mechanics_and_Fracture_Analysis", "<your-api-key>")
await client.connect()
# Calculate density from mass and volume
mass = 100 # kg
volume = 0.05 # m³
density = mass / volume
print(f"Density: {density} kg/m³")
await client.disconnect()
