mass moment of inertia - L23

Question 1

angular acceleration

Answer 1

resistance to rotate is related to mass and the distribution of mass around the axis of rotation.

Question 2

why is the ratio of muscular strength to segmental moments of inertia important contributor to performance capability in rotational sports?

Answer 2

as it balances the athletes ability to generate force and the resistance they will feel of movement.

Question 3

what does mass moment of inertia describe ?

Answer 3

an objects rotating about its centre of mass.

Question 4

what is the radius of gyration

Answer 4

if we are measuring the mass moment of inertia of somethng that is not rotatinf about an axis that is not the at the CoM we will use this for the remote calculations.

Question 5

remote axis of rotation

Answer 5

rotating around something that is not the CoM.

Question 6

local axis

Answer 6

around the CoM.

Question 7

does a greater mass moment of inertia make it more difficult to change its anguklar velocity

Answer 7

yes.
