Description
Study of Benjamin Robins’ machine for determining the velocity of bullets. Headed: ‘Experiments relating to The Force of Gunpowder, the Velocity of Musket & Cannon shot, & the resistance of the Air’. Below ‘Fig. 1st.
Projectiles were aimed from various distances at the square plate which was intended to pivot on an axis – the arc length described by the pendulum allowed Robins to calculate the speed of the bullet.
Benjamin Robins (1707-1751) British mathematician and military engineer was elected a Fellow of the Royal Society in 1727.
