(a)
To sketch:
The repeat unit structure of polychlorotrifluoroethylene.
(a)

Answer to Problem 1QAP
The repeat unit structure of polychlorotrifluoroethylene is sketched and shown in
Figure 2.
Explanation of Solution
The repeat unit of polychlorotrifluoroethylene is arrived from the repeat unit of polyethylene.
The repeat unit molecular structure of polyethylene is shown in Figure 1.
The repeat unit of polyethylene contains two carbon atoms and four hydrogen atoms.
The replacement of three hydrogen atoms by three fluorine atoms and one hydrogen atom by one chlorine atom gives the repeat unit molecular structure of polychlorotrifluoroethylene that is shown in Figure 2.
(b)
To sketch:
The repeat unit structure of poly (vinyl alcohol).

- 1. Consider the following LTI system. d²y dy du +7 +6y= -- +2u, t≥0 dt² dt dt a) What is the impulse response of the system? Recall, h(t) = L-¹(H(s)). b) What are poles and zeros of the system? c) Suppose the initial condition of the system is y(0) = 1 and y'(0) = 4. What is the zero-input response of the system? d) Consider an input u(t) = (1 + et) 1(t) to the system. What is the zero-state response of the system for this input? e) Suppose, the initial condition was y(0) = -2 and y'(0) = -8 and the input is u(t)=(1+e) 1(t). What will be the total response of the system? You should be able to answer this using the linearity property of the system and your answers in part b and part c without taking any inverse Laplace transform.arrow_forwardGiven a normally distributed variable X with mean 4 and standard deviation 2, fi (a) P(X5). (d) P(1.8arrow_forwardIn MATLAB write out a program to integrate the equations of motion of a rigid body. The inertia matrix is given by I = [125 0 0; 0 100 0; 0 0 75] which is a diagonal, where diag operator provides a matrix with given elements placed on its diagonal. Consider three cases where the body rotates 1 rad/sec about each principal axis. Integrate the resulting motion and study the angular rates and the resulting attitude (use any attitude coordinates). For each principal axis case, assume first that a pure spin about the principal axis is performed, and then repeat the simulation where a small 0.1 rad/sec motion is present about another principal axis. Discuss the stability of each motion. The code should produce a total of 6 simulations results when it is ran.arrow_forwardIn 32-bit MSAM, You were given the following negative array. write a program that converts each array element to its positive representation.
