Question
A homogeneous disk of 5 cm radius and 5 kg mass rotates on an axle AB of length 0.25 m and rotates
about a fixed point A. The disk is constrained to roll on a horizontal floor.
A
0.25 m
OA. 100 rad/s in the x direction and -20 rad/s in the z direction
C
Given that the disk rotates counterclockwise at a rate of 100 rad/s about axle AB, the angular velocity of the
disk is
(Hint: use the right hand rule to determine positive and negative direction.)
OB. 100 rad/s in the x direction and +20 rad/s in the y direction
OC. 100 rad/s in the x direction and -20 rad/s in the y direction
B
OD. 100 rad/s in the x direction and +20 rad/s in the z direction
