Answer:

Standard Armored cable(AC) or Metal-clad cable(MC)

Explanation:

Standard Armored Cable (AC) or Metal-Clad Cable (MC) may be used based on the definition of words "wet or dry locations" in areas that may be temporarily exposed to the elements such as rain during construction.

Dry locations should not be confused with damp locations which are protected from these elements and water saturation or moisture. Some damp locations may include open porches, barns, under canopies, etc.

Wet locations occur in places where direct burial in the ground, in concrete, etc may occur. These are places where water or other liquid saturation is very possible, or in places that are always opened to these elements.

Why is the reflection step in the engineering process the most important step?

Monica [59]

Reflection helps designers to learn from their experiences, to integrate and co-ordinate different aspects of a design situation, to judge the progress of the design process, to evaluate interactions with the design context, and to plan suitable future design activities.

Determine the constant speed at which the cable at A must be drawn in by the motor in order to hoist the load 6 m in 1.5s

zlopas [31]

Answer:

4m/s

Explanation:

We know that power supplied by the motor should be equal to the rate at which energy is increased of the mass that is to be hoisted

Mathematically

$Power_{motor} } =\frac{Energy }{time}$ \

We also know that Power = force x velocity ..................(i)

The force supplied by the motor should be equal to the weight (mg) of the block since we lift the against a force equal to weight of load

=> power = mg x Velocity........(ii)

While hoisting the load at at constant speed only the potential energy of the mass increases

Thus Potential energy = Mass x g x H...................(iii)

where

g = accleration due to gravity (9.81m/s2)

H = Height to which the load is hoisted

Equating equations (ii) and (iii) we get

m x g x v = $\frac{mgh}{t}$

thus we get v = H/t

Applying values we get

v = 6/1.5 = 4m/s
