Answer:
I think D is the correct answer
Explanation:
hope it is
The shear stress at any given point y1 along the height of the cross section is calculated by: where Ic = b·h3/12 is the centroidal moment of inertia of the cross section. The maximum shear stress occurs at the neutral axis of the beam and is calculated by: where A = b·h is the area of the cross section.
A. All the answers are correct (All of the above).
Answer:
1) a. Customers requiring AC electric power transmission for powering remote devices which may include a subsea transmission system where power is distributed to subsea devices
b. Customers that utilize commutator-type motors
2) The primary voltage is 150 volts
Explanation:
The parameters given are;
Number of primary winding,
= 50 turns
Number of secondary winding,
= 150 turns
Voltage in secondary winding,
= 450 volts
Voltage in primary winding = 
The relation between
,
,
and
is as follows;

Which gives;

From which we have;

The primary voltage = 150 volts.
