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:
The answer is below
Explanation:
Given that:
The area of the plates is 6 m by 0.030 m, Therefore the area = 6 m × 0.03 m = 0.18 m²
the relative permittivity of dielectric (εr) is 7.0
Permittivity of free space (εo) = 8.854 × 10^(-12)
capacitance of 100uF
potential difference (V) of 12V
d = separation between plate
The capacitance (C) of a capacitor is given by:
The electric field between plates is given as:
E = V /d
