Answer:
A = 10, B = -45
Explanation:
Given a voltage source of the form 
the correspondent phasor is of the form 
. Note that the phasor form is only considered for sources expressed in a cosine form. IN this case, since the question is only asking for the phasor of the voltage form, the way the other devices are connected is neglected and do not affect the answer. Then, to get the phasor of the voltage source, we need to express it in a cosine form. To do so, the following trigonometric equation is used 
Therefore, the voltage source, in terms of cosine, is equivalent to 
, so the correspondent phasor form is 
.

Answer:
Each of the metal specimens HAS an indentation near the center to ensure that the fracture point would occur in this region. Tension tests WERE CONDUCTED as follows. Two pieces of reflective tape WERE PLACED approximately 1 inch apart in the center of the specimen where the indentation 4 WAS LOCATED. The width and the thickness of the specimen at this location WAS MEASURED using a Vernier caliper. Then the specimen WAS SECURED in the MTS Load Frame. A laser extensometer WAS PLACED into position to measure the deformation of the specimen. The laser extensometer WAS USED to measure the original distance between the pieces of reflective tape. The MTS WAS SET to elongate the specimen one tenth of an inch every minute.
