Assignment:
As a part of an exercise regime,,a lady lifts herself up from standing position at the rest,wth wait distributed normally across the soles of her feet,onto tiptoe(standing on 2 feet)which muscle group she is exercising ?is it possible to achieve the static equilibrium by loading only one muscle group?if so draw a free body diagram showing the key components that you think might be involved in this process ,showing where forces are generated and reached.for your chosen configuration , compute the forces in the active muscle as a function of the angle of lift of the foot,theta,and of the fixed lengths of the relevant bones.
