Suppose your bathroom sink is clogged and you have decided to try and unclog it by pushing a wire into the drain. You have several types of wire available around the house, some insulated and some not. Which of the following wire characteristics would you need to consider in selecting a wire for the job?

The wire characteristics are listed as follows:

a. Immunity to electrical noise
b. Color of the insulation
c. Resistance of the insulation to salt water
d. Resistance of the insulation to fire
e. Cost
f. Stiffness
g. Ease of stripping the insulation -
h. Weight
i. Availability
j. Strength
k. Resistance to high temperatures
l. Resistance to stretching

Answers

Answer 1

Answer:

stiffness ( f )

weight ( h )

availability ( i )

strength ( j )

resistance to stretching ( l )

Explanation:

The wire characteristics to be considered for the job would be the mechanical characteristics only . therefore the characteristics to consider are :

stiffness: since you want to use the wire to unclog the sink it is necessary you consider the flexibility of the wire in order to achieve what you want weight: the lighter the wire the easier it can be used for the jobAvailability : the wire has to be very close and readily available for the job it will be used forStrength: The wire has to be strong enough so that it doesn't break inside the sinkResistance to stretching : The wire needs to have a high ductility
