Question
Angular impulse is the product of force and the time that force Is applied torque and the time that torque is applied angular inertia and angular momentum mass and angular velocity force and torque To determine the length of a moment arm. one would measure the perpendicular distance from the axis of rotation to the force's line of action the perpendicular distance from the axis of rotation to the force's point of application the vertical distance from the axis of rotation to the force's line of action the vertical distance from the axis of rotation to the force's point of application the vertical component of force During angular motion, what is the relationship between the length of the moment arm and the torque created? The shorter the moment arm. the greater the force The longer the moment arm the, greater the torque Torque and force remain constant. The moment arm is equal to the product of force and torque. Moment arm length and torque are not related. The center-directed acceleration of a spinning object (e.g., a bail on a string) is called centrifugal acceleration centripetal acceleration. tangential acceleration angular acceleration Pierzynski acceleration When knee flexion is increased (heel brought to buttocks) during running, the moment of inertia of the lower extremity about the hip is increased is decreased remains the same depends on the anthropometrie characteristics of the leg Moment of inertia cannot be measured about the hipExplanation / Answer
Here ,
19)
Using second law of motion
angular Impulse = Torque applied * time
hence , the angular impulse is the product of b) torque and the time that torque is applied.
20)
as the moment of force is given as
torque = force * perpendicular distance
the correct option is a) the perpendicular distance from the line of force action
21)
as the moment of force is given as
torque = force * perpendicular distance
hence ,the correct option is
b) the longer the arm , the greater the force
22)
for the centre directed acceleration of the object
the acceleration is called
b)centripetal acceleration
