Mass of each top member Ms = .05 kg

Mass of each bottom member Mbs = .05 kg

Displacement after which the mast is self-deployable Zd = .2 m

Solution:

From equations (3.5) to (3.9)

Number of levels on each side N=2

Number of plates C = 9

Weight of the top member of the strut Wts = .9810 kg

Weight of the plate Wp = 1.962 kg

Total length of strut when deployed Lmax = 1.414 m

3.4.1

From equations (3.13) and (3.14)

Minimum deflection of the springs dmin = .1514 m

Minimum stiffness of spring in level 1 K1 =11 N/m

Minimum stiffness of spring in level 2 K2 = 28.6 N/m

3.4.2

From equations (3.16) to (3.21)

For level 1

Stiffness of the spring K = 12.5 N/m
