Figure illustrates the proportions in male (m) anatomy. The displacement d1m from the bottom of the feet to the navel has a height of 61 cm. The displacement d2m from the navel to the tip of the middle finger has a length of 77 cm. If the vector sum of the displacements d1 and d2 in each case is 108 kN and θ is equal to 27°. Determine the length from the tip of the middle finger to the other tip of the middle finger in cm.
