A circular disk with radius r and mass m

is xed at an angle on a cantilever beam without mass. The

cantilever beam is rotated at a constant angular velocity f and,

additionally, the circular disc rotates at a constant angular velocity.

Complete both the components of the angular momentum vec

tor with respect to the center of mass of the circular disc LS and

the components of the angular momentum vector of the circular

disk with respect to the point

P$.$

Hint: The total angular momentum around the point

LS $+$LPR$.$

Given:

r $=40$ cm$,$

rel $=20$ s $1,$

m$=30$ kg$,$ l $=90$ cm$,=60.$

Insert the correct solution at an accurracy of four signi cant numbers into the corresponding elds:

Evaluate the missing components of the angular momentum terms
