Build a scale model crane using interactive components like a jib arm, hydraulic cylinder, and platform. Analyze torque and forces to balance the system. Adjust positions and calculate required force for equilibrium.
Access geologic time scale data with a simple interface. View and scroll through eons, eras, periods, epochs, and ages. Select specific time divisions to see their names and numerical dates.
Simulate a lab environment with an Erlenmeyer flask, burette, stirring plate, and titrant dropper. Perform of hydrochloric acid to neutralize carbonate deposits. Adjust solution volumes and observe reaction progress.
