My FavoriteSimulation is to check the Durability of Drone body.

Here, we consider the direction of load of complete assembly in the downward direction, and at a time of take off when propellers will rotate; there will be a pressure at the other end of 4 Arms in the upward direction.

The assembly arms will feel the pressure from both the sides; and we can calculate for how many cycles it will be possible (by checking the log of life).  After sometime the body might bend or break.   

Scenario Progression: 

Please watch the complete procedure in detail in the attached video:

Explore the results:

The Minimum Log of Life is 2.79.

So minimum 616 Cycles are possible in this drone body.
