Drafting has been around a long time. We can safely assume that since we’ve had a tool in our hands, we’ve been describing plans and technical representations and doodling ideas. Let’s take a closer aspect at drafting and its advance from an under-the-radar part of the method to a very developed skill set.

Explanation

•  1970s – The beginning computer-aided design systems were included in the industry. Following the design engineers tried the learning curve of using CAD, their performance and productivity went through the roof. Over time, CAD software became affordable and more user-friendly, and its fame grew.

•   1990s – CAD software was expanded further to include 3-D characteristics, and quickly the technical designs of the past enhanced increasingly simulated and accessible to engineer.

Answer:

investment 10 years from now is $1,238,000 .

Explanation:

given data

sum = $500,000

rate = 12% =0.12

total time = 10 year

solution

as present value After 2 years from now is $500,000

so time period is now = 8 year  ( 10 - 2 )

so we apply future value formula that is

Future value  = present value × [tex](1+r)^{t}[/tex]   ............1

put here value we get

Future value  = $500,000 × [tex](1+0.12)^{8}[/tex]  

Future value  = $500,000 × 2.476

Future value  = $1,238,000  

so investment 10 years from now is $1,238,000 .

The systems found on Electric car are- battery pack, Electric motors, Differentials etc.

The systems found on internal combustion vvehicles include- Engine, Flywheel, Propeller shaft, Governor, Pistons and Crankshaft among several other components.

Explanation:

Electrical cars are associated with an electric motor, battery pack and other car accessories. Their propulsive power sets them apart from conventional vehicles. They are driven by a battery pack which is rechargeable and in turn drives the electric motors connected to each of the wheels.  

These cars are also conspicuous with the absence of a propeller shaft which provides the power to conventional gasoline vehicles. Instead of the shaft, individual motors present side by the wheels drive them. Depending on the car’s drive ratio (either 2*4 or 4*4), the electric motors present them with sufficient power. Other equipment such as differentials, steering and control unit remains more or less same.

Internal Combustion car- They are the class of conventional vehicles powered by the burning of gasoline in the sealed engine of the car. They are either petrol, diesel variant or gas-powered. The working can be explained as follows-

Gasoline fuel with high calorific value burns in a controlled environment to produce gas which drives the piston which is in turn connected to the crankshaft. The crankshaft is responsible for turning the vertical motion of the piston to the rotatory motion of a ball lever.

Several mechanical components such as spark plugs, differentials, flywheel, governors etc make up for the controlled environment in which the fuel is allowed to burn.

During World War I, riveting remained the primary method for ship construction and repair, with no clear indication that it was replaced during the conflict. Advances post-war led to welding becoming the preferred technique due to its stronger joints and efficiencies.

During World War I, the process that began to replace riveting for ship repair was not explicitly mentioned in the provided text, indicating that riveting remained a significant method of construction and repair during this period. However, industrial and technological advancements during and following World War I led to the development and adoption of welding techniques which eventually became more prominent in shipbuilding and repair. Welding offered advantages over riveting, such as stronger joints and a reduction in labor and materials. Nevertheless, during World War I itself, the text highlights the intensive use of riveting, with contests to speed up production and techniques to ensure parts made in different locations could be assembled efficiently on site.

The contribution of riveting to shipbuilding during World War I is underscored by the record set by John Omir and the detailed planning required to assemble ships like the SS Agawam, with parts prefabricated and riveted in various locations before assembly. This period marked a significant effort to boost production in the face of enemy threats, laying the groundwork for future shifts towards welding in ship construction and repair.

Answer:

Peggy Annette Whitson was born February 9, 1960, Mount Ayr, Iowa, U.S.

She was the first female commander of the International Space Station.

She holds the record among American astronauts and among women for spending the most time in space, nearly 666 days.

She received a B.S. in biology and chemistry from Iowa Wesleyan College in Mount Pleasant, Iowa, in 1981 and a doctorate in biochemistry from Rice University in Houston in 1985.

She flew into space for the first time on June 5, 2002, as a flight engineer on Expedition 5 to the ISS, aboard the space shuttle Endeavour on mission STS-111.

She, from 2009 to 2012, Whitson was chief of the Astronaut Office, which oversees all NASA astronaut activities, including crew selection and training.

She was the first woman and the first civilian to hold that position.

She was sent into space 3 times.

Her total of 10 career spacewalks and their combined duration of 60 hours 21 minutes were records for a female astronaut.

She retired from NASA in 2018.

The problem is a hypergeometric distribution scenario, where we calculate the probability of a batch being rejected based on the presence of defective items in a random sample.

The question is about calculating the probability that a batch of somatropin doses gets rejected based on a quality control sampling test. To find this probability, we need to consider the number of defective samples in the batch and the number of samples taken for the test. Given that there are 11 defective doses out of 225, we can calculate the probability that none of the 15 randomly chosen samples are defective (which means the batch is accepted) and subtract this probability from 1 to get the probability of the batch being rejected (due to finding at least one defective sample in the test).

Since this is an application of hypergeometric distribution, the exact calculation requires combinatorial analysis, which would provide the probability of picking 0 defective doses in a sample of 15 from a lot of 225 doses which includes 11 defects.

White Stern light

Explanation:

According to boating regulations, navigation lights must be used for safety purposes when operating water vessels especially during the night.

The boating regulations for operating sailboats, specify that a white stern light must be used during hours from sunset to sun rise. This is to indicate the presence of the sea craft on the ocean, as well as its direction.

A stern light is a white light placed as closely as practical at the stern shining constantly. It covers an angle of 135 degrees, and helps show the direction of the boat.

The lights should be used is white sternlight.

A sailboat is operating under sail at night is known to be one where the operator of that sailboat is said to be operating under sails at darkness and so their sidelights should be (red - green) and stern light (white).

When they are said  to be less than 20 meters in length, the three lights can be use altogether  at or near the top of the mast.

Amount of energy required = 292.6 kJ

Explanation:

Amount of energy required is given by the equation ,

Q = m × C ×ΔT

where m is the mass of the water = 2000 g

C is the specific heat of water = 4.18 J/g°C

ΔT = Temperature difference = 60 - 25 = 35 °C

Applying these values in the above equation, we will get,

Q = 2000 g × 4.18 J/g°C × 35°C

  = 292600 J

When joule is divided by 1000 we will get the amount of energy in kJ.

[tex]$ Q = \frac{292600}{1000} = 292.6 kJ[/tex]

So the energy required to raise the temperature of the water is 292.6 kJ.

Answer:

It is because constraints applied automatic by the software (CAD) are supposed to control relationships and geometry between lines, arcs and circles while those manually added are supposed to control the geometry to behave in the manner the user likes the sketch to appear when drawing.

Explanation:

CAD software enables creating sketches using the program by automatic allowing geometric constraints to perform the tasks.Geometry in lines, circles, and other geometric features show collaborating relation that facilitate sketching in the program.For example, two end points appear to make lines remain perpendicular.Other geometric constraints are parallel, and equal.However, the user can manually apply geometric constraints to a sketch to force the geometry in a manner that is suitable to the sketch drawn.That is why a user must manually apply others.

Explanation:

She will spend $25 million in 3 years at 10% interest is a case of Future Value of Annuity.

Therefore,

FV = A*((1+r)^n-1)/r

Where A = 25,000,000

r=10%=0.1

n=3

FV= 25000000*((1+0.1)^3-1)/0.1

FV=25000000*(1.331-1)/0.1

FV=25000000*(0.331/0.1)

FV=25000000*3.31

FV=$82,750,000

So it is estimated that 20million cars passes through the toll per year

Therefore,

Toll per vehicle per year = 82750000/2000000

=$4.14
