A study by physics students at the University of Leicester explores the dynamics of jousting, revealing that a knight on horseback delivers an impact akin to a car crash. By modeling the combined mass of knight, horse, and equipment, the study estimates the energy transferred during a jousting strike. When galloping at 13.4 m/s, a knight can produce up to 153,000 newtons of force, though the lance typically breaks under stress at 103,000 newtons. Ultimately, the study highlights the intense forces involved in historical jousting events and their implications for safety.
A knight galloping at 13.4 m/s delivers an impact similar to a car crash, transferring 1,030 newton-seconds of momentum and 53,000 joules of energy.
The analysis shows that a full gallop generates 7,700 newton-seconds of momentum, delivering a staggering 153,000 newtons of force, though the lance can only withstand 103,000 newtons.
The study emphasizes how a jousting lance, braced by devices, efficiently transmits momentum during impact, leading to a significant transfer of force and energy.
This research reveals the violent nature of jousting impacts, akin to the energy released in minor automobile collisions, underscoring the sport's physical dangers.
