Answer:
The axial force is 
Explanation:
From the question we are told that
The diameter of the shaft steel is 
The length of the cylindrical bushing 
The outer diameter of the cylindrical bushing is 
The diametral interference is 
The coefficient of friction is 
The Young modulus of steel is 
The diametral interference is mathematically represented as

Where
is the pressure (stress) on the two object held together
So making
the subject

Substituting values


Now he axial force required is

Where A is the area which is mathematically evaluated as

So 
Substituting values


Answer:
c. nine times as low.
Explanation:
Sound intensity is defined as the acoustic power transferred by a sound wave per unit of normal area to the direction of propagation:

Since the sound wave has a spherical wavefront of radius r, then the area is given by:

Here r is the distance from the source of the sound. Thus sound intensity decreases as:

Because of Gravity, Basically a force so strong it constantly pulls us to the earth with 1 G (Maybe 100 pounds of force constantly pulling us to the earth)
