ME360 - Dynamic Systems Prof. Gillespie - Fall 2010 HW 3 - Due Sept 23 Problem 1 Problem 2.3, page 70. For convenience, I will repeat the problem statement here: For the mass shown in Figure 2.1.3b (in the body of Chapter 2), m = 10kg, φ =25 , v (0) = 2m/s and μ = 0 . 3. Determine whether the mass comes to rest if (a) f 1 = 100N and (b) f 1 = 50N. If the mass comes to rest, compute the time at which it stops. Problem 2 Problem 2.19, page 74 in the book. (Note extra part below, not included in book) The geared system shown in Figure P2.19 (same in previous edition) is similar to that used in some vehicle transmissions. The speed ratios (which are the ratios of the gear radii) are ω 2 ω 1 = 3 ω 3 ω 2 = 3 5 ω 4 ω 3 = 13 11 (1) a) Determine the overall speed ratio ω 4 1 b) Derive the equation of motion in terms of the velocity ω 4 , with the torque T 1 as the input. Neglect the inertias of the gears and the shafts. c) In addition, derive the equation of motion in terms of the velocity ω 4 when there is a viscous friction force acting on inertia I with torque

    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.
