Because the components in the 2–3 subsystem are connected in parallel, that subsystem will function if at least one of the two individual components functions. For the entire system to function, component 1 must function and so must the 2–3 subsystem. The experiment consists of determining the condition of each component [S (success) for a functioning component and F (failure) for a nonfunctioning component]. (Enter your answers in set notation. Enter EMPTY or ∅ for the empty set.) There us a graph shown in the pictures. Questions are posted on the pictures too.arrow_forward

- This paragraph from the text defines the term "controllable". The concept of rank plays an important role in the design of engineering control systems, such as the space shuttle system mentioned in this chapter's introductory example. A state-space model of a control system includes a difference equation of the form xk+1 = Axk+ Buk for k = = 0, 1,... (1) where A is n xn, B is n xm, {x} is a sequence of "state vectors" in R" that describe the state of the system at discrete times, and {u} is a control, or input, sequence. The pair (A, B) is said to be controllable if rank B AB A² B ... A"-¹B] = n (2) The matrix that appears in (2) is called the controllability matrix for the system. If (A, B) is controllable, then the system can be controlled, or driven from the state 0 to any specified state v (in R") in at most n steps, simply by choosing an appropriate control sequence in R" Determine of the following matrix pair is controllable: [0.9 1.0 0 A = 0 -0.9 0 B = , 0 0 0.5]arrow_forward2. Find the solution set to the following system of linear equations using Gauss-Jordan elimination. (2.x1 + 7x2 – 12.x3 = -9 x1 + 2x2 – 3.x3 = 0 3x1 + 5x2 – 7x3 = 3 - Determine the rank of the coefficient matrix and the augmented matrix.arrow_forwardA system consists of two identical pumps, #1 and #2. If one pump fails, the system will still operate. However, because of the added strain, the remaining pump is now more likely to fail than was originally the case. That is, r = P(#2 fails | #1 fails) > P(#2 fails) = q. If at least one pump fails by the end of the pump design life in 12% of all systems and both pumps fail during that period in only 8%, what is the probability that pump #1 will fail during the pump design life?arrow_forward

In their current inven- tory, a total of 48 planks of wood are left. Each sofa needs four planks of wood to be made while each table needs two planks of wood to be made. The company earns a profit of hundred pesos where P(x, y) = 12xy for selling a units of sofas and y units of tables. With their current inventory of woods, how many sofas and tables are needed to be produced to maximize their profit? (Use the Lagrange method of optimization.)arrow_forward1.
