The mass center

G

of the slender bar of mass

0.87kg

and length

0.37m

is falling vertically with a velocity

v=1.8(m)/(s)

at the instant depicted. Calculate the angular momentum of the bar about point

O

if the angular velocity of the bar is

(a)\\\\omega _(a)=10.9ra(d)/(s)

clockwise and (b)

\\\\omega _(b)=10.9ra(d)/(s)

counterclockwise. The angular momentum is positive if counterclockwise, negative if clockwise.\ Answers:\ (a)

H_(0)=

kg*(m^(2))/(s)

\ (b)

H_(0)=

kg*(m^(2))/(s)

The mass center G of the slender bar of mass 0.87kg and length 0.37m is falling vertically with a velocity V=1.8m/s at the instant depicted. Calculate the angular momentum of the bar about point O if the angular velocity of the bar is (a)a=10.9rad/sclockwise and (b) b=10.9rad/s counterclockwise. The angular momentum is positive if counterclockwise, negative if clockwise. Answers: (a) H0= kgm2/s (b) HO= kgm2/s
