The adjacent diagram displays the joint reaction force between the acetabulum and femoral head for the right leg during single leg stance. Also shown are the abductor muscle force (AMF), the weight of the body above the level of the stance hip (W) and their corresponding moment arms with respect to the joint centre (D and D1). If the right leg weighs 1/6 of total body weight, the ratio of D1 to D is 2.4, and AMF is angled at 30 degrees relative to the vertical, calculate the:Abductor muscle force (2 marks).Hip joint reaction force (2 marks).Express both answers as multiples of total body weight <くHpreactionforceAbductorBody weightThe adjacent diagram displays the joint reaction forcebetween the acetabulum and femoral head for the rightleg during single leg stance.
