The figure below shows a man of mass 60 kg exiting from a bathtub where the right root contacts
the ground and experiences a vertical ground reaction force component of 400 N, a side–to–side
force component of 45 N directed towards the bath and a backwards force of 20 N. If these forces
can be considered to act at the centre of pressure, P, then;
(i) Calculate the joint resultant moments at the knee and the hip joints in the sagittal plane.
Ignore inertial effects (5)
(ii) Calculate the joint resultant moments at the knee and the hip joints in the frontal plane.
Ignore inertial effects (5)
