A weight of 18,000 lb is supported on a rectangular baseplate that is 9-in. wide and 2-ft long. The baseplate rests on a concrete slab. Determine the stress that the baseplate exerts on the concrete slab. Express your answer in units of (a) lb/in.2 and (b) lb/ft2 (precision of 1 for (a) and of 1000 for (b)).
Answer:
Explanation:
To find the stress that the baseplate exerts on the concrete slab, we need to calculate the pressure distribution on the baseplate. The weight is distributed over an area of 9 in. × 24 in. = 216 in.2.
The stress is the force per unit area, so we can calculate it by dividing the weight by the area:
(a) Stress in lb/in.2:
18,000 lb / 216 in.2 ≈ 83.33 lb/in.2
(b) Stress in lb/ft2:
83.33 lb/in.2 × (12 in./ft)2 × 1 ft2/144 in.2 ≈ 583.3 lb/ft2
Therefore, the stress that the baseplate exerts on the concrete slab is approximately 83.33 lb/in.2 or 583.3 lb/ft2.

A water turbine is to be designed to produce 27MW when running at 93.7 rev/min
under a head of 16.5m. A model turbine with an output of 37.5kW is tested under
dynamically similar conditions with a head of 4.9m . Calculate the:
a. model speed; b. scale ratio; c. assuming a model efficiency of 88%, estimate the volume
flow rate through the model; and d. if it is estimated that the force on the thrust bearing of
the full-size machine is 7.0GN , determine the bearing thrust of the model.
The Answers for the given question are as follow:
a. The model speed is approximately 31.62 rev/min.
b. The scale ratio is approximately 0.0417.
c. The estimated volume flow rate through the model is approximately 943.44 m^3/s.
d. The bearing thrust of the model is approximately 9.72 kN.
To calculate the required values for the water turbine model, we can utilize the concept of dynamic similarity.
a. To find the model speed, we can use the principle of geometric similarity, which states that the ratio of speeds is equal to the ratio of the square roots of the head. Thus:
Model speed = (√(Model head))/(√(Full-size head)) * Full-size speed
= (√4.9/√16.5) * 93.7 rev/min
= 31.62 rev/min
b. The scale ratio can be determined using the equation:
Scale ratio = (√(Model power))/(√(Full-size power))
= (√37.5kW)/(√27MW)
≈ 0.0417
c. To estimate the volume flow rate through the model, we can use the power equation:
Model power = (Model efficiency) * (Volume flow rate) * (Model head) * (Gravity)
37.5kW = 0.88 * (Volume flow rate) * 4.9m * (9.81m/s^2)
Solving for the volume flow rate:
Volume flow rate = 37.5kW / (0.88 * 4.9m * 9.81m/s^2)
≈ 943.44 m^3/s
d. To calculate the bearing thrust of the model, we can use the principle of force similarity:
Bearing thrust model = (Model power / Full-size power) * Full-size bearing thrust
= (37.5kW / 27MW) * 7.0GN
≈ 9.72kN

why a biomedical engineer would need to dilute any solutions?
Biomedical engineers may need to dilute solutions for several reasons. One common reason is to adjust the concentration of a particular substance to a desired level for experimental or clinical purposes.
Dilution allows for precise control over the concentration of a solution, enabling researchers or healthcare professionals to study the effects of different concentrations of substances on biological systems.
In biomedical engineering, dilution is often employed when working with drugs or therapeutic agents. By diluting a concentrated drug solution, engineers can create different dosages suitable for specific applications. This is crucial for ensuring patient safety and achieving desired therapeutic outcomes.
Additionally, dilution is necessary for calibration and quality control purposes in biomedical engineering. Diluting stock solutions of known concentrations can generate a range of standard solutions used to calibrate instruments, verify measurement techniques, or assess the accuracy of analytical methods.
Dilution plays a critical role in ensuring accurate and reliable data collection, analysis, and experimentation within the field of biomedical engineering.
In summary, dilution is an essential technique for biomedical engineers as it allows them to control the concentration of substances, customize drug dosages, and maintain accuracy in calibration and quality control processes, all of which are vital for research, development, and healthcare applications.

You are tasked with a designing a circuit that accepts a stream of binary digits, and that outputs a 0 whenever the pattern 10 takes place. Otherwise, the output is 1.
Part A [2 marks] Draw the state diagram for the above description. Use a Moore model, i.e., a Finite State Machine (FSM) where the outputs are specified within the states.
Part B [2 marks] Assign binary values to your states using an encoding that requires the minimum number of digits.
Part C [2 marks] Obtain the binary-coded state table.
Part D [4 marks] Assuming the use of JK flip-flops, derive both the flip-flop input equations in addition to the output equation.
Part E [4 marks] In the space below, draw the logic diagram of the circuit you designed above.
To draw the state diagram for the given description, we need to identify the states and transitions based on the behavior of the circuit. In this case, we have two states: State A (output = 1) and State B (output = 0).
The transitions are as follows:
From State A, when the input is '1', transition to State B.From State B, when the input is '0', transition to State A.Part B:
To assign binary values to the states, we can use a binary encoding that requires the minimum number of digits. Since we have two states, we can assign '0' to State A and '1' to State B.
Part C:
Based on the states and transitions, we can create a binary-coded state table. Here's an example of how the table would look:
| Present State | Input | Next State | Output |
|---------------|-------|------------|--------|
| A | 0 | A | 1 |
| A | 1 | B | 1 |
| B | 0 | A | 1 |
| B | 1 | B | 0 |
Part D:
Assuming the use of JK flip-flops, we can derive the flip-flop input equations and the output equation based on the state table. Here's an example of the equations:
J_A = 0
K_A = 0
J_B = 1
K_B = Q_A
Output = Q_A
Part E:
To draw the logic diagram of the circuit, we would use the derived flip-flop input equations along with the output equation to implement the circuit using logic gates.
Thus, the circuit would include JK flip-flops, AND gates, and possibly other gates depending on the specific implementation.

What is the most important part of a successful Election Day?
Answer: voting of course
Explanation:
An electrical circuit is being discussed. Technician A states that if resistance is added, the current will
decrease. Technician B states that if voltage is decreased, amperage would increase. Who is correct?
Select one:
O a. Technician A only
b. Technician B only
O c. Both Technicians A and B
O d. Neither Technician A nor B
Based on the fact that Technician A states that if resistance is added, the current will decrease. Technician B states that if the voltage is decreased, amperage would increase, Both Technicians A and B are correct.
How can this be explained?
Resistance and voltage have an inverse relationship in an electrical circuit. This relationship is described by Ohm's Law, which states that the current (I) flowing through a circuit is equal to the voltage (V) divided by the resistance (R). The formula for Ohm's Law is I = V/R
Hence, it can be seen that When resistance is added to a circuit, the current flowing through the circuit will decrease because the formula I=V/R and as resistance goes up the current goes down.
Similarly, when voltage is decreased in a circuit, the current will increase, because again using Ohm's law I = V/R the current is inversely proportional to the voltage thus as voltage decreases current increases.
So option c. "Both Technicians A and B" are correct.
