In casting experiments performed using a certain alloy.
jeyben [28]
Answer:
A) Cm = 2.232 s/mm²
B) Time taken to solidify = 74.3 seconds
Explanation:
(A) Since a side is 50mm and all sides of a cube are equal, thus, Volume of the cube is;V = 50 x 50 x 50 = 125,000 mm³
There are 6 faces of the cube, thus Surface Area A = 6 x (50 x 50) = 15,000 mm²
So, Volume/Area = (V/A) = 125,000/15,000 = 8.333 mm
Cm is given by the formula; Cm =[Tts] /(V/A)² where Tts is time taken to solidify and it's 155 seconds in the question. Thus;
Cm = 155/(8.333)²= 2.232 s/mm²
(B) For;Cylindrical casting with D = 30 mm and L = 50 mm.;
Volume of cylinder is;
V = (πD²L) /4
So,V = (π x 30² x 50)/4 = 35,343mm³
Surface area of cylinder is;
A = (2πD²)/4 + (πDL)
Thus, A = ((π x 30²)/2) + (π x 30 x 50) = 6126 mm²
Volume/Area is;
V/A = 35,343/6126 = 5.77 mm
Same alloy and mold type was hsed as in a above, thus, Cm is still 2.232 s/mm²
Since Cm =[Tts] /(V/A)²
Making Tts the subject, we have;
Tts =Cm x (V/A)²
Tts = 2.232 x (5.77)² = 74.3 seconds

  • Part a requires you to find second decile and 8th decile
  • For second decile there are 30 elements for second decile:

(a) Locator: 0.2*30 = 6

    Round up to 7

    20% decile = 31

  • For 8th decile

    Locator: 0.8*30 = 24

    Round up to 25

    80% decile = 54

(b) To determine 67th percentile

    Locator : 0.67^30 = 20.1

    Round up to 22

    67% percentile = 48

Points A and B lie on a circle with radius 1, and arc ⌢AB has a length of π/3. What fraction of the circumference of the circle
maks197457 [2]

Answer:

1/6

Explanation:

The circumference of a circle is denoted by: C = 2πr, where r is the radius. Here, we see that the radius is 1, so plug this in:

C = 2πr

C = 2π * 1 = 2π

We see that arc AB has length π/3, so to find the fraction of the circumference this is, divide π/3 by 2π:

(π/3) ÷ 2π = (π/3) * (1/2π) = 1/6

Thus, the answer is 1/6.
