3. A biomechanical model of the lumbar region of the human trunk is shown. The forces acting in the fourmuscle groups consist of FR = 35 N for the rectus, Fo= 45 N for the oblique, FL = 23 N for the lumbarlatissimus dorsi and FE = 32 N for the erector spinae. These loadings are symmetric with respect to the y-zplane. Determine the resultant force equivalent to the given parallel force system and locate its point ofapplication (x,y) on the trunk.FLFEFR15 mm75 mm30 mm40 mm45 mm

The wheels, axle, and handles of a wheelbarrow weigh W = 55 N. The load chamber and its contents weigh WL = 623 N. The drawing shows these two forces in two different wheelbarrow designs.
