Here is the online simulation that will help you get intuitive understanding of the torques and balance. Being with the introduction to explore the options offered by this simulation, get familiar with the concept of balance and navigation.
Move to the balance lab to find the mass of at least four mystery objects (see the instruction below)
1. Open "Balance Lab" (Figure 1)
2. Navigate to Mystery Objects ABCD (Figure 2) or EFGH (Figure 3)
3. Find the weights of the objects (two from the ABCD group and two from the EFGH group).
Figure 1.
Figure 2. ABCD Mystery Objects.
Figure 3. EFGH Mystery Objects.
1. Open the Game (Figure 4)
2. Play beginning with Level 1. The minimum requirement is to get 5 stars on Level 3 and Level 4 (Figure 5). If you feel confident, you can start from level 3. If you are getting frustrated by level 3, go back to level 1 or 2 and learn on less demanding balances.
3. Take a screenshot of Level 3 and level 4 achievements.
