Question

Force platform is a popular tool for locomotion (i.e., running) analysis in biomechanical research. If Shannon is asked to run through a force platform, the force exerted by the platform on her foot is recorded in the early phase of her stance during a running stride as: -180x + 600y + 60z, where +x = forward, +y = upward, and +z = lateral. a. What was the magnitude of the resultant ground reaction force? b. What was the magnitude of the resultant force acting in the sagittal plane? c. What was the direction of the resultant force acting in the transverse plane?

In the middle of the stance phase during a running stride, the force exerted by the ground on the foot of the runner was -268i + 821j + 92k, where +i represents forward, +j represents upward, and +k represents lateral. a. What was the magnitude of the resultant ground reaction force? b. What was the magnitude of the resultant force acting in the frontal plane? c. What was the direction of the resultant force acting in the transverse plane?

The Force of Running Biomechanical research has shown that when a $67-mathrm{kg}$ person is running, the force exerted on each foot as it strikes the ground can be as great as $2300 mathrm{N}$. (a) What is the ratio of the force exerted on the foot by the ground to the person's body weight? (b) If the only forces acting on the person are (i) the force exerted by the ground and (ii) the person's weight, what are the magnitude and direction of the person's acceleration? (c) If the acceleration found in part (b) acts for $10.0 mathrm{ms},$ what is the resulting change in the vertical component of the person's velocity?

a-biomechanical-model-of-the-lumbar-region-of-the-human-trunk-is-shown-the-forces-acting-in-the-fo-2

A biomechanical model of the lumbar region of the human trunk is shown. The forces acting in the four muscle groups consist of $F_{R}=35 \mathrm{N}$ for the rectus, $F_{o}=45 \mathrm{N}$ for the oblique, $F_{L}=23 \mathrm{N}$ for the lumbar latissimus dorsi, and $F_{E}=32 \mathrm{N}$ for the erector spinae. These loadings are symmetric with respect to the $y-z$ plane. Replace this system of parallel forces by an equivalent force and couple moment acting at the spine, point $O .$ Express the results in Cartesian vector form.
