As a manufacturing automation engineer, you are asked to design a control system to automate a bottle-filler machine for bottled

water. Empty bottles are moved into position beneath the filler nozzle one at time by a conveyor moved by a stepping motor. Once a bottle is in position underneath the nozzle, the control system actuates a valve (using an actuator) allowing the water to flow into the bottle. A sensor measures the flow rate and sends it to the control system. The control system determines when to close the valve (using an actuator) to achieve the desired volume of water in the bottle based on the flow rate. The valve is closed via a signal from the control system and the stepping motor advances the next bottle. Using the list of sensors and actuators given in the course lectures, design and describe what are the appropriate sensors and actuator to be used to automate the water-filler machine for bottled water. Include in your description of the control system, the type of input/output signals (such as binary, analog, etc.), and how the system is to utilize the input/output data.

Solnce55 [7]

Answer:

a) 2.18 m/s^2

b) 9.83 m/s

Explanation:

The flywheel has a moment of inertia

J = m * k^2

Where

J: moment of inertia

k: radius of gyration

In this case:

J = 144 * 0.45^2 = 29.2 kg*m^2

The block is attached through a wire that is wrapped around the wheel. The weight of the block causes a torque.

T = p * r

r is the radius of the wheel.

T = m1 * g * r

T = 18 * 9.81 * 0.6 = 106 N*m

The torque will cause an acceleration on the flywheel:

T = J * γ

γ = T/J

γ = 106/29.2 = 3.63 rad/s^2

SInce the block is attached to the wheel the acceleration of the block is the same as the tangential acceleration at the eddge of the wheel:

at = γ * r

at = 3.63 * 0.6 = 2.81 m/s^2

Now that we know the acceleration of the block we can forget about the flywheel.

The equation for uniformly accelerated movement is:

X(t) = X0 + V0*t + 1/2*a*t^2

We can set a frame of reference that has X0 = 0, V0 = 0 and the X axis points in the direction the block will move. Then:

X(t) = 1/2*a*t^2

Rearranging

t^2 = 2*X(t)/a

t = \sqrt{\frac{2*X(t)}{a}}

t = \sqrt{\frac{2*18}{2.81}} = 3.6 s

It will reach the 1.8 m in 3.6 s.

Now we use the equation for speed under constant acceleration:

V(t) = V0 + a*t

V(3.6) = 2.81 * 3.6 = 9.83 m/s

Which regulations are related to guard rail height and dimensions and uniformity of stairs?
galina1969 [7]

Answer:

C.

structural safety

Explanation:

Guards protecting floor surfaces must be 36 inches in height, while guards for stairs must be 34 inches in height measured vertically from the tread nosing. A guard may also serve as the required handrail (34 to 38 inches high) provided the top rail meets the requirements for grip size.

If you are sampling a 50Hz signal, what is the minimum sampling rate necessary to prevent aliasing?Why?
horsena [70]

Answer:

100Hz

Explanation:

The minimum sampling rate to prevent aliasing is at least double your sample frequency.

50*2 = 100Hz

This is called the Nyquist Sampling Rate if you wanna learn more about it.
