British Pendulum Slip Tester - What is it? How does it work?

If the striking part is called the foot then surely the bar it’s connected to is the leg not the arm

While that sounds like it would make sense, we confirm that in this case the part connected to the Mechanical Foot is called the "Pendulum Arm" 😁
