Lever#

Lever block converts force and velocity based on the lever arm ratio. The block can be connected to both force and velocity source blocks. The direction of motion of the second arm is controlled by Force transmission (1):

(1)#\[\begin{split} F_2=\frac{F_1}{C_l};\\ v_2=v_1\cdot C_l, \end{split}\]

where:

\(F_1\) – force applied to the first arm, [N];

\(F_2\) – force applied to the second arm, [N];

\(C_l\) – ratio of the length of the second arm to the first;

\(v_1\) – first arm speed, [m/s];

\(v_2\) – second arm speed, [m/s].
