Question
The first observation of injection locking was in two of these devices. For these devices, the Airy condition can be approximately satisfied by deadbeat escapements. A classic example of a control system with a cart-pole apparatus involves maintaining the stability of an “inverted” one of these devices. Harmonographs draw Lissajous (“LEASE-ah-zhu”) curves from the motion of these devices. (*) Angular velocity is proportional to the sine of latitude in a type of these devices that provided the first evidence of the Earth’s rotation. The small angle approximation equates two pi times the square root of length over little g to the period of one of these devices. For 10 points, name these devices that consist of a suspended mass swinging from a fixed point. ■END■
