Which of the following statements most accurately describes the circuit?

Any programmer who writes a Diophantine equation solver must occasionally encounter an infinite loop.

Sergio [31]

Answer: True

Explanation:

An Infinite loop occurs in a computer programming when a sequence of instructions run endlessly without stopping until there is an external intervention, this intervention could be pull or plug. It is also known as endless loop. It occurs due to using of variables that are not properly updated or when there is an error in looping condition.

A large television company (CFR) contacts a technology provider, GET, Inc., to arrange a meeting to discuss an upgrade of its ex

ELEN [110]

Answer:

In the passage, it has been mentioned that the president of CFR received the letter from GET, who offered them to install the network servers at the cost of $5 million and the president of CFR also accept it. Although the GET will charge 50 percent more charges after getting the news of heavy tax on technology providers, I will not accept it. As a president of CFR my argument will be that I will ask them (GET) to install the servers at the earlier price that the GET offers before heavy taxation, otherwise, I will reject the offer as I had not formally agreed. Because, the president already informed them about the acceptance of the offer.

My other argument will be that if the GET will not accept my previous proposal, I will go to another technology provider, who can offer the service at a lower cost in comparison to the GET.

You are performing a machining operation that approximates orthogonal cutting. Given that the chip thickness prior to chip forma

Mnenie [13.5K]

Answer:

A)

shear plane angle = 31.98°

shear strain = cot ( 31.98° ) + tan ( 31.98 - 10 )

B) shear strength = 7339.78

Explanation:

a) Determine the shear plane angle and shear strain

Given data :

Chip thickness before chip formation = 0.5 inches

Chip thickness after separation = 1.125 inches

rake angle ( ∝ ) = 10°

shear plane angle : Tan ∅ = $\frac{rcos\alpha }{1-sin\alpha }$ ----- ( 1 )

r = chip thickness ratio = 0.5 / 1.125 = 0.4444

back to equation 1 : Tan ∅ = ( 0.444 ) * cos 10 / 1 - sin 10

Tan ∅ = 0.4444 * 0.9848 / 1 - 0.1736 = 0.5296

hence ∅ = tan^-1 ( 0.5296 ) = 31.98°

shear strain : R = cot ∅ + tan ( ∅ - ∝ ) ---------- ( 1 )

R = cot ( 31.98° ) + tan ( 31.98 - 10 )

B) determine the shear strength of the material

cutting force = 1559 N

thrust force = 1271 N

width of cut ( diameter ) = 3.0 mm

shear strength = c + σ.tan ∅

c = cohesion force = 1271 * 3 = 3813

σ = normal stress = F / A = 1559 / π/4 * ( 0.5 )^2 = 1559 / 0.1963 = 7941.94

hence : shear strength of material = 3813 + 7941.94 * 0.6244 = 7339.78
