A disk and a ring both homogeneous with masses M1=0.94 kg and M2=M1/6 and radii R1=0.36 m and R2=R1/2, respectively, are coupled by an ideal C strap, as shown in the figure below . At a given moment, a work of modulus W=35 J is performed on the system that, starting from rest, makes the disk and the ring rotate around their symmetry axes.

A proposal is made to use a giant spring in the bottom of an elevator shaft as a means of safely "catching" a falling elevator car. The car freefalls until it hits a spring, which is then compressed until the car stops. The car's loaded weight is 20.0 kN. The elevator will service 20 floors. Distance between floors is 4 m. The deceleration rate of the car should not exceed 10 g's as it is being stopped. (a) determine the requirements for the spring constant and the amount the spring will compress in order to catch the falling car in the worst-case scenario. (b) what do you think about this proposal? Is it practical?

A windmill turns a series of slender rods fixed about one end . They are initially 2 meters long, and go at a speed of 15 revolutions per minute. I suggested making the blades 1m long to reduce the cross-sectional area of the windmill, keeping the mass the same for mechanical stress consistency. How fast are the windmill blades going now, in revolutions per minute?
