Design PrioritiesPerformance Mark Equation:
Priority list:1. Gearbox Dimension Size2. Speed at which Gearbox pulls weight3. Power used by gearbox
(Every controllable variable in equation was prioritised by their index)

Calculated coefficient of static friction = ~0.3
Calculated projected required output force = ~92N
Estimated gear ratio (simple) based on motor specs and projected required output torque = 1:34
Design Consideration – Friction and Torque
