As you recall, the Logic Schematic for Lab2&3 ('Smart ECC Transportation 'Bus' with Robotic Arm: 4-Bit Microcomputer) was very complex and difficult because we used Logic Gates. How would an Arduino UNO Board using an 8-Bit Microcontroller improve or simplify the design and testing? Hint: Mention every experience you had in the Lab2&3 and Imagine if you used Arduino instead.

Hot water (cph = 4188 J/kg·K) with a mass flow rate of 2.5 kg/s at 100°C enters a thin-walled concentric tube counterflow heat exchanger with a surface area of 23 m2 and an overall heat transfer coefficient of 1000 W/m2 ·K. Cold water (cpc = 4178 J/kg·K) with a mass flow rate of 5 kg/s enters the heat exchanger at 20°C. Determine
(a) the heat transfer rate for the heat exchanger and
(b) the outlet temperatures of the cold and hot fluids. After a period of operation, the overall heat transfer coefficient is reduced to 500 W/m2 ·K, so determine
(c) the fouling factor that caused the reduction in the overall heat transfer coefficient.

A cylindrical specimen of a hypothetical metal alloy is stressed in compression. If its original and final diameters are 19.636 and 19.661 mm, respectively, and its final length is 75.9 mm, calculate its original length if the deformation is totally elastic. The elastic and shear moduli for this alloy are 108 GPa and 37.1 GPa, respectively.

Block B starts from rest, block A moves with a constant acceleration, and slider block C moves to the right with a constant acceleration of 75 mm/s2. Knowing that at t = 2 s the velocities of B and C are 480 mm/s downward and 280 mm/s to the right, respectively, use kinematics to determine:
a. The acceleration of A and B
b. The initial velocities of A and C
c. The change in positions of slider C after 3 s.

Which statements describe codominance? Select three options. Traits are usually dominant. Traits are neither dominant nor recessive. Offspring exhibit an intermediate form of alleles from the parents. Both alleles, one from each parent, are expressed in offspring. Codominance involves the interaction of two alleles.

You are asked to study the causal effect of hours spent on employee training (measured in hours per worker per week) in a manufacturing plant on the productivity of its workers (output per worker per hour). Write in the box the option letter (a, b, c or d) on the right that best describes the statement on the left. Choose a random group of employees to receive ten hours per week in additional training for a period of four weeks. Then, estimate the difference in productivity between workers who received the additional training and those that did not
