Answer:
Diameter of riser =6.02 mm
Explanation:
Given that
Dimensions of rectangular plate is 200mm x 100mm x 20mm.
Volume of rectangle V= 200 x 100 x 20 
Surface area of rectangle A
A=2(200 x 100+100 x 20 +20 x 200)
So V/A=7.69
We know that
Solidification times given as
-----1
Lets take diameter of riser is d
Given that riser is in spherical shape so V/A=d/6
And
Time for solidification of rectangle is 3.5 min then time for solidificartion of riser is 4.2 min.
Lets take 
Now from equation 1
So by solving this d=6.02 mm
So the diameter of riser is 6.02 mm.

Answer:
Fatigue factor of safety is 2.0267
Explanation:
Solution is attached below.
Answer:
let number = 0
while number < 1
begin
print "Enter a positive integer: "
read number
end
end_while
find and print number's factors:
let prime = TRUE
let currentFactor = 2
let lastFactor = the square root of number truncated
to an integer value
while currentFactor <= lastFactor
begin
if number is evenly divisible by currentFactor
begin
print currentFactor
let number = number / currentFactor
end
else
let currentFactor = currentFactor + 1
end_if
end
end_while
print a message if number is prime:
if prime == TRUE
print "Your number is prime"
end_if
