Question $1[40-$Marks$]$:

If a lateral$-$to$-$medial load is applied to the foot, a counteracting moment is produced at

the knee joint in a lateral$-$medial plane, which stretches the lateral collateral ligament and

the cruciate ligaments. Estimate the moment produced by cruciate ligaments to that

produced by the lateral collateral ligament. Use the force$-$deflection characteristics of the

ligaments in your solution.

Note: Communicate with class notes.

$M_C=F_C{L}_C$ and $M_L=F_L{L}_L$

From force $F-$displacement $,F=k$

$($k: rigidity coefficient$)$
