Use the algorithm below to answer the four questions:

ALGORITHM Mystery(n)

//Input: A nonnegative integer n

S ← 0

for i ← 1 to n do

S ← S + i * i

return S

a.) What does this algorithm compute?

b. ) What is its basic operation?

c.) How many times is the basic operation executed? (Solve the summation.)

d.) What is the efficiency of this algorithm?

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
