Small blocks, each with a mass “m”, are clamped to each end and at the center of a rod with length L of negligible mass. Compute the moment of inertia of the system about an axis perpendicular to the rod and passing through the rod a.) at one end of the rod. b.) at the center of the rod c.) at a point ¼ the length from the center.

Unformatted text preview: 2. If the system is rotating at 30 rpm, find the kinetic energy of the system in question 1 if the system is rotating about an axis that is perpendicular to the rod and passing through the rod a.) at one end of the rod. b.) at the center of the rod c.) at a point ¼ the length from the center. 3. Two hanging masses m 1 = 25 kg and m 2 = 20 kg are tied to a string, of negligible mass,which passes over a pulley. The masses are at the same height when released from rest. What is the magnitude of the velocity of the two masses after m 1 has dropped a distance of 0.5 meters? Treat the pulley as a thin disk of mass of 10 kg and a radius of 5.0 cm. 4. A rod has mass M and length L and a uniform density. Calculate the moment of inertia using: a.) I = ∫ r 2 dm b.) the parallel axis theorem....

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
