The parliament building tower clock in london, has hour and minute hands with lengths of 2.70 m and 4.50 m and masses of 60.0 kg and 100 kg, respectively. calculate the total angular momentum of these hands about the center point. treat the hands as long, thin uniform rods.

Explanation:

Given

length of hour hand is 2.7m

length if minute hand is 4.5m

And Moment of inertia of a rod about its one of a end

for hour hand is

Angular speed for minute hand

Angular moment(L) is given

For hour hand
