Question
Dynamics
Arm BC has a mass of 14 kg, and the
moment of intertia about its center
of mass is 2 kg m2. Point B is sta-
PCM
tionary.
Arm BC is initially aligned with
the horizontal X-axis with zero an-
AL
-→X
gular velocity and a constant couple
M applied at B causes the arm tO
rotate upward.
When it is in the position shown, its counter-clockwise angular velocity
is 1.2 rad/s.
Figure 3: PCM=0.21 m, 0=31°
Determine M.
