You're standing with both feet on a force plate, your arm extended directly to the side and up, holding a length of rope in the hand of the extended arm. The CP and CM (centers of pressure and mass, respectively) are show for this posture. Someone walks up to you and starts pulling on the rope in the direction shown in diagram B. Despite their pulling, you're able to maintain the exact same body position (AKA posture). Explain what you expect to happen to each of the quantities listed due to the presence of Fpull. First, list your guess for each quantity, then check if you're right using mechanical rationale. Quantity Ffy Ffx CP location CM location Initial Guess Mechanical rationale: (you will need a second sheet to show this for each quantity. Provide mechanical rationale for Ffy, Ffx, and CP location, but NOT CM location) B F Fpull Ffx Ffy X You're standing with both feet on a force plate, your arm extended directly to the side and up, holding a length of rope in the hand of the extended arm.
