A.
find the area under the curve first
![\int\limits^{\sqrt[3]{\pi}}_0 {x sin(x^3)} \, dx =0.61157809233184](https://tex.z-dn.net/?f=%20%5Cint%5Climits%5E%7B%5Csqrt%5B3%5D%7B%5Cpi%7D%7D_0%20%7Bx%20sin%28x%5E3%29%7D%20%5C%2C%20dx%20%3D0.61157809233184)
then solve c∛π=0.61157809233184
c≈0.41757577488026
round if necicary

alright, solve where they itnersect
x²=y=mx
x²=mx
x²-mx=0
x(x-m)=0
set to zero
x=0
x-m=0
x=m
they intersect at x=0 and x=m
which one is on top?
hmm
y=mx will always be on top (I don't know how to prove that but it's on top)
so we do

solve
  
so

m³=48
m=2∛6
 
        
             
        
        
        
Answer:
A. equal compression between cylinders.
Explanation:
Equal compression between cylinders lead to uniform propelling of the shaft which in turn results into smooth motion of the shaft hence a smoothly operating engine.
In case of unequal compression, there shall be experienced unequal propelling which shall in turn result to rough engine  operation
