Report
1. An object’s ability to resist motion is also known as what? Inertia 2. The moment of inertial can be described by which of the following? A measure of resistance to angular motion 3. Torque multiplied by time equals what? Angular Impulse 4. Angular moment is equal to what? Moment of inertia * angular velocity 5. If the knee has coordinates of (1.2, 2.7) and the ankle has coordinates of (1.5, 2.1), with the shank weighing 3.2kg, what is the moment of inertia of the shank about the proximal end point? (k% = 0.528) Knee = (1.2, 2.7), ankle = (1.5, 2.1), shank mass = 3.2kg, k% = 0.528 L = √ (x1 - x2) 2 + (y1 - y2) 2 I p = m (%k * L) 2 L = √ (1.2 - 1.5) 2 + (2.7 - 2.1) 2 I p = 3.2 (0.528 * 0.6708) 2 L = 0.6708 I p = 0.40kgm 2 0.40kgm 2 6. Which of the following would reduce the moment of inertia? Moving the mass closer to the axis of rotation 7. Which of the following is true when angular momentum is conserved? Summation of external torques equals to zero 8. During a flipping motion, how would you increase their moment of inertia of the whole body? Stick their arms and legs further from the COM 9. Torque applied over a given time period is known as what? Angular impulse 10. If a body segment has an angular velocity of 125 rads/s and a moment of inertia of 0.41kgm 2 , how much angular impulse does it have? 51.25Nms
