Inclined plane, wood engraving, published in 1880
Inclined plane - a flat supporting surface tilted at an angle, used as an aid for raising or lowering a load. Inclined planes are widely used to move heavy loads over vertical obstacles

Atwoods machine, wood engraving, published in 1880
The Atwoods machine was invented in 1784 by the English mathematician George Atwood (1745 - 1807) as a laboratory experiment to verify the mechanical laws of motion with constant acceleration

G-Force: The Unseen Force Defying Human Limits, from Early Rocket Sled Experiments to Astronaut Training Witness the evolution of our understanding of G-Force, the measure of acceleration felt by an object or person, through intriguing milestones in history. In the 1950s, Northrop Corporation's Rocket Sled, Sonic Wind I, pushed the boundaries with speeds exceeding 1,000 mph, subjecting test subjects to extreme G-Forces. Early scientific illustrations, like wood engravings of an inclined plane from 1880 and an Atwood's machine from the same year, laid the groundwork for understanding the fundamental principles of physics involving forces. John Stapp, a pioneering US aviation researcher, reached a record-breaking 632 mph in 1954, experiencing a mind-bending 46.2 Gs. During the historic Vostok 1 spacecraft re-entry in 1961, cosmonaut Yuri Gagarin endured intense G-Forces, proving humans could withstand the rigors of space travel. Artificial gravity platforms and astronaut training centrifuges continue to play crucial roles in preparing future explorers for the challenges of space, ensuring the triumph of human curiosity and ingenuity over the unseen force of G-Force.
