Figure Legend:
Support force Fm (equal to mg) as a function of the adjustment of r for the versions with adjustment angles of φ=0deg, φ=90deg, and φ=180deg, respectively (spring stiffness k=1 and link length L=1000mm), where it is assumed that all three versions have the same maximum extension of the spring (in this example Δsmax=L) so as to obtain equal maximum support force
