Two technicians are discussing battery load testing. Technician A says that if the battery fails the load test, it is bad and
should be replaced. Technician B says if it fails the load test, it should be fully charged and the test repeated. Who is
correct?
Select one:
a. Technician A
b. Technician B
o
c. Both Technicians A and B
O
d. Neither Technician A nor B
Answer:
The correct technician is;
b. Technician B
Explanation:
During battery load testing, the amperes produced by a battery that is at least 75 percent charged when a load tester applies a calibrated load of half the cold cranking amp rating of the battery for 15 seconds is measured. A battery that gives a voltage reading of above 9.6 volts all through the test is a good battery. However, if the voltage reading goes lower than 9.6 volts at about the end of the test, the battery could be 'bad', or may require recharging and retesting, where it was not on full charge before the test
Therefore, Technician B is correct
Shane's 100-watt radio draws 7 amps of current on a 120-volt circuit. What is the resistance in the radio?
Answer:
Resistance, R = 2.04 Ohms.
Explanation:
Given the following data;
Current = 7 amps
Circuit voltage = 120 Volts
Power = 100 Watts
To find the resistance;
First of all, we would calculate the potential difference (voltage level) used by the radio.
Power = current * voltage
100 = 7 * voltage
Voltage = 100/7
Voltage = 14.29 Volts
Next, we solve for the resistance of the radio;
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
[tex] V = IR[/tex]
Where;
V represents voltage measured in voltage.
I represents current measured in amperes.
R represents resistance measured in ohms.
Substituting into the formula, we have;
[tex] 14.29 = 7*R[/tex]
[tex] R = \frac {14.29}{7} [/tex]
Resistance, R = 2.04 Ohms.
Can anyone explain what the effects of positive and negative camber, toe angle, and caster on front-wheel-drive, rear-wheel drive, all-wheel drive, and 4 wheel drive cars, trucks, and SUVs are? Please include examples.
A positive camber is good for keeping a recreational vehicle stable, while the negative camber is better for allowing high performance vehicles to have a better ability to turn corners faster and accurately. The toe angle affects directional control, turning response and tire tread life. Toe-related tread wear will cause a "feathering" wear pattern across the tread. If too much toe-in is present, the feathering will angle toward the center of the vehicle. Increasing the amount of positive caster will increase steering effort and straight line tracking, as well as improve high speed stability and cornering effectiveness. Positive caster also increases tire lean when cornering (almost like having more negative camber) as the steering angle is increased.

Using the Fundamental Canons of the NSPE Code of Ethics craft a 10 sentence response detailing whether or not the engineer is
acting ethically, why their actions are ethical or not, and what actions, if any, should they take to correct their potentially unethical
behavior. Provide evidence from the Fundamental Canons and justify your response with clear reasoning.
Engineer A received a Bachelor of Science degree in 1940 from a recognized engineering curriculum and subsequently was registered as a
professional engineer in two states. Later, he was awarded an earned "Professional Degree from the same institution. In 1960, he received a Ph.D.
degree from an organization that awards degrees on the basis of correspondence without requiring any form of personal attendance or study at the
institution and is regarded by state authorities as a diploma mill." Engineer A has since listed his Ph.D. degree among his academic qualifications in
brochures, correspondence, and otherwise, without indicating its nature.
