Dear student,
Please see the answer in the attachment.
Thank you.
(3) Using the complete controllability theorem show that the model of the two masses attached by...
Homework 7: Undamped, 2-DOF System 1. A system with two masses of which the origins are at the SEPs is shown in Figure 1. The mass of m2 is acted by the external force of f(t). Assume that the cable between the two springs, k2 and k3 is not stretchable. Solve the following problems (a) Draw free-body diagrams for the two masses and derive their EOMs (b) Represent the EOMs in a matrix fornm (c) Find the undamped, natural frequencies...
Please show all work for a high rated answer. Two blocks are attached to one another, as shown, by means of a massless cord that passes over a massless frictionless pulley. Block 1 (mass m1, = 10.0 kg) is connected to a spring with spring constant k = 100 N/m, and block 2 (mass m2 = 20.0 kg) sits on a frictionless ramp that makes an angle theta = 30.0 degree with the horizontal. The coefficient of kinetic friction between...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
