1.17 The tripod shown in Fig. 1.73 is used for mounting an electronic instrument that finds the distance between two points in space. The legs of the tripod are located symmetrically about the mid-vertical axis, each leg making an angle a with the vertical. If each leg has a length / and axial stiffness k, find the equivalent spring stiffness of the tripod in the verti- cal direction.
