Circular farm uses rotational power with Mechanical Bearing and Linear Chassis. Farm requires Gearshift, Clutch, Filter, and Rotation Force. Mechanical Saws harvest trees, Deployers plant saplings. Farm can be extended to grow different tree types simultaneously
Worm drive combines worm screw with worm wheel for perpendicular motion translation. Invented by Archimedes, possibly during First Punic War. Gear ratio equals worm wheel tooth count to one. Drive axes are at 90° angles
Circulates engine oil under pressure to lubricate bearings and cool engine. Pressurized oil powers small actuators and hydraulic systems. Generates pressure of about 10 psi per 1000 RPM, peaking at 55-65 psi
Hydraulic machines use liquid fluid power to perform work. Pascal's law states pressure transmitted equally in all directions. Systems use incompressible liquid instead of compressible gases
Recoil is backward thrust generated when a gun is discharged. Recoil follows conservation of momentum principle. Projectile and gun accelerate at tens to hundreds megapascals. Heavier and faster projectiles generate more recoil
Axle connects wheels and provides support for bearings. Bottom bracket contains pedals and crankset with adjustable or cartridge bearings. Frame serves as mechanical core with various attachment points. Fork integrates frame to handlebars for steering
