Abstract

In some examples, an apparatus can include an arm, a cam connected to the arm, a first spring located around a first strut, where the first spring is oriented at a first angle relative to a base of the apparatus and the first strut is connected to the cam, a second spring located around a second strut, where the second spring is oriented at a second angle relative to the base of the apparatus and the second strut is connected to the cam, where the first spring and the second spring linearly compress in response to rotation of the arm from a vertical orientation to a horizontal orientation relative to the base of the apparatus.
