Chapter 8, Problem 1RQ
To determine
Identify if the component is normally open or normally closed when the component is to be used for the function of start.
Expert Solution & Answer
Explanation of Solution
There are circumstances where it is desirable to have more than one start/stop push button when operating a motor.
When a component is used for the function of start then the component is generally open and is connected parallel to the existing start button. If either of the start button is pressed, the circuit will be completed and the coil will be energized.

The 2-mass system shown below depicts a disk which rotates about its center and has rotational
moment of inertia Jo and radius r. The angular displacement of the disk is given by 0. The spring
with constant k₂ is attached to the disk at a distance from the center. The mass m has linear
displacement & and is subject to an external force u. When the system is at equilibrium, the spring
forces due to k₁ and k₂ are zero. Neglect gravity and aerodynamic drag in this problem. You may
assume the small angle approximation which implies (i) that the springs and dampers remain in
their horizontal / vertical configurations and (ii) that the linear displacement d of a point on the
edge of the disk can be approximated by d≈re.

- A linear system is one that satisfies the principle of superposition. In other words, if an input u₁ yields the output y₁, and an input u2 yields the output y2, the system is said to be linear if a com- bination of the inputs u = u₁ + u2 yield the sum of the outputs y = y1 + y2. Using this fact, determine the output y(t) of the following linear system: given the input: P(s) = = Y(s) U(s) = s+1 s+10 u(t) = e−2+ sin(t) =earrow_forwardThe manometer fluid in the figure given below is mercury where D = 3 in and h = 1 in.
