8. A voltmeter measures a voltage drop of 600 V across a heating element while an
ammeter reads the current through it as 2.0 A. What is the resistance of the
heating coil.
Answer:
How do I calculate voltage drop?
To calculate voltage drop, E, across a component, you need to know the resistance of the component and the current thru it. Ohm's Law is E=I⋅R , which tells us to then multiply I by R . E is the voltage across the component also known as voltage drop

Why are manhole covers round in most of the cases?
Answer:
Explanation:
Because there are no angles for alignment, the round shape makes these heavy covers easier to put back on once they're taken off. Round covers are also easier to manufacture. But the main reason manhole covers are round is so they won't accidentally fall into the manhole itself.
If a 1500 V load is ac coupled to the output in Figure 9–60, what is the resulting output voltage (rms) when a 50 mV rms input is applied? gm = 5000 mS.
The resulting output voltage (rms) when a 50 mV rms input applied is -187.5 mV.
What is rms voltage?Root Mean Square Voltage is the amount of AC power which produces the same heating effect as DC Power would have produced.
Vo = -gm x Vi (Rd II Rl )
Vo = -5000 x 10⁻⁶ x 50 x 10⁻³ x (1.5k II 1.5k )
Vo = -25 x 10⁻² x 750 x 10⁻³
Vo = -187.5 mV
Hence, resulting output voltage (rms) when a 50 mV rms input applied is -187.5 mV.

A cutting tool wears out with a time to failure that is normally distributed with a mean of 10 working days and a standard deviation of 2.5 days. (a) determine its design life for a reliability of 0.99. (b) find the reliability if the tool is replaced every day; every two days; every five days. (c) determine the probability that the cutting tool will last one more day given it has been in use for 5 days.
Using the normalized distribution it is possible to calculate the value of Z score and for cases where there is a 99% chance, so Zscore is -3.6 and X= 16.45.
What are the types of probability distribution?This curve determines the probability of the event associated with it occurring. The Gaussian distribution is the most common, hence it is known as the Normal Distribution. The area under the distribution curve is always equal to 1.0.
The formula for this distribution can be described as:
[tex]Z score = \frac{x-\mu}{\sigma}[/tex]
Where:
x= Probability density functionμ= Meanσ= Standard DeviationIn this case,
[tex]Z score =\frac{1-10}{2.5} \\Z score = -3.6[/tex]
P-value from Z-Table will be P(x<1) = 0.00015911
For 99% we have that z will be 2.58, so
[tex]2.58=\frac{x-10}{2.5}\\x = 16.45[/tex]

a pipe discharges wine into a 1.5m diameter tank. Another pipe (15cm diameter), located near the base of the, is used to discharge wine out of the tank. Calculate the volumetric flow rate into the tank if the wine level remains constant at 2.5m.
The volumetric flow rate into the tank if the wine level remains constant at 2.5m is; 0.1232 m³/s
How to Calculate Volumetric Flow Rate?The formula for volumetric flow rate is;
V' = area * velocity
We are given;
Diameter; d = 15 cm = 0.15 m
Thus;
Area; A = (π/4)d²
A = (π/4)(0.15)²
A = 0.0176 m²
Velocity is; v = √(2gh)
v = √(2 * 9.8 * 2.5)
v = 7 m/s
Thus volumetric flow rate is;
V' = 0.0176 * 7
V' = 0.1232 m³/s

The factor of safety is very important in design. It is determined by comparing the allowable stress to actual stress. What is known if the range of the factor of safety is between .75 and 1
Explanation:
A factor of safety is the load-carrying capacity of a system beyond what the system actually supports. Bridges, buildings, safety equipment, and fall protection all start with a factor of safety.
Simply put, the safety factor is how much stronger a system is than required. The factor of safety is the backbone of all structures and safety equipment and originates with engineers. In the planning phase of all structures and safety equipment, engineers determine the required overload from any object to remain safe in the event of an emergency.
For reliability, structures are typically built stronger than necessary. This is in case a structure experiences a heavier-than-expected load. This is a factor of safety. Ultimately, the amount of stress and overload a structure can handle comes down to the material used to build it.
Determining the factor of safety:
Engineers perform strength tests to determine how much weight a material can handle. Certain materials are more ductile than others, meaning they deform to pressure before breaking more so than others, like brittle materials. Brittle materials simply break once they meet the maximum force.
Ductile materials use yield strength to determine the safety factor. Brittle materials use the ultimate strength.
Yield strength: Determines the safety factor until the start of deformation.
Ultimate strength: Determines the safety factor until failure.
Ductile materials often test the factor of safety against yield and ultimate strengths while brittle materials usually only calculate the ultimate safety factor since the yield and ultimate values are often so close.
The necessary factor of safety of any structure determines the materials used. If a structure has a high required factor of safety, then engineers use a ductile material to build it. The realized factor of safety determines the amount of material used.
Required (design factor): A constant value imposed by law or standard. A structure is required to meet this value at a minimum.

A motor car shaft consists of a steel tube 30 mm internal diameter and 4 mm thick. The engine develops 10 kW at 2000 r.p.m. Find the maximum shear stress in the tube when the power is transmitted through a 4: 1 gearing.
The maximum shear stress in the tube when the power is transmitted through a 4: 1 gearing is 28.98 MPa.
What is power?Power is the energy transferred per unit time.
Torque is find out by
P = 2πNT/60
10000 = 2π x 2000 x T / 60
T =47.74 N.m
The gear ratio Ne / Ns =4/1
Ns =2000/4 = 500
Ts =Ps x 60/(2π x 500)
Ts =190.96 N.m
Maximum shear stress τ = 16/π x (T / (d₀⁴ - d₁⁴))
τ max =T/J x D/2
where d₁ = 30mm = 0.03 m
d₀ = 30 +(2x 4) = 38mm =0.038 m
Substitute the values into the equation, we get
τ max = 16 x 190.96 x 0.038 /π x (0.038⁴ - 0.03⁴)
τ max = 28.98 MPa.
Thus, the maximum shear stress in the tube is 28.98 MPa.

Thus, Lack of diversity would limit opportunities for new viewpoints, original ideas, and varied experiences. There might not be enough intellectual and emotional stimulation and repetitious conversations and exchanges.
Because everyone would address problems and obstacles in the same way, life might become predictable and static.
Although conflicts and disagreements may be less frequent, the lack of diverse opinions may make it more difficult to come up with original solutions.
