A1.1 m diameter wagon wheel consists of a thin rim having a mass of 10 kg and six spokes each having a mass of 1.1 kg. determine the moment of inertia of the wagon wheel for rotation about its axis.

What is the angular momentum of the bar about the axle?

Wo small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at ? 0 = 1.16 rad/s as the two telescoping booms are extended from r1 = 1.18 m to r2 = 4.69 m at a constant rate over a period of 124 seconds. the small 19-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible. determine the necessary thrust t for each jet as a function of time where t = 0 is the time when the telescoping action is begun. after you have the general expression for t, answer the questions. show work.

What is the role of the water cycle in maintaining freshwater levels in lake and rivers?
