 ### Suggested Steps
 Open the "DroneDesign_StudentProjectTemplate.mlx" Live Script in MATLAB as a starting point for your project.
-1. Gather your starter assumptions so you can plug in numbers later.
-    - Consider a quadcopter drone (4 motors) with a max takeoff weight of 2kg (including the payload)
-    - Each motor can provide up to 1kg thrust
-    - Arm length (you choose)
-    - Material (you choose e.g. aluminum or carbon, look up typical material properties)
-    - Acceleration due to gravity: $g = 9.81 m/s^2$
-2. Assume each arm of the drone is modeled as a beam or truss element. Using simplified geometry, propose 1-2 designs that will minimize weight but maximize payload capacity.
-3. Calculate the maximum payload capacity.
-    - First, calculate the net upward force available from motors
-    - Next, calculate the estimated frame weight from material and geometry
-    - Finally, calculate max payload capacity while maintaining equilibrium
-4. Use MATLAB to simulate force distribution and moments (*optional*: perform a finite element analysis by first creating your drone design in a CAD tool and importing the .stl file into MATLAB)
-    - Plot shear/moment diagrams for drone arms
-    - Calculate center of mass to ensure stable flight
-5. Create a simple animation or visualization showing drone geometry and payload lift

 ### Expected Results for Project Solution
-1. Sketches of proposed designs
-2. Numerical value for maximum payload capacity estimated for each design
-3. Shear/moment diagrams for drone arms and center of mass for different force distributions and moments simulated
-4. Animation or visualization of drone geometry and payload lift
 
-### Optional Extensions (advanced)
-- Optimize the structure (e.g. arm thickness) using MATLAB's Optimization Toolbox to maximize payload given material constraints
-- Simulate a dropped payload and resulting shift in center of mass
-- Use Simulink and Simscape for dynamic simulation under lifting conditions

 ### Learning Outcomes
-- Apply statics concepts (equilibrium, free‑body diagrams, trusses, and moments) to a real engineering system.
-- Analyze structural loads, material choices and design tradeoffs with MATLAB-based computation of forces, moments, and center-of-mass positions.
-- Evaluate structual design concepts through simulation, with an emphasis on understanding how payload placement and structural design influence drone stability and performance.
