(2) two borehole wall reaction force vectors produced by, size is also equal to fluid pressure and is multiplied by plunger floor space, and direction is from center of circle O
Point to another controlling switch (2) direction.
Due to controlling switch S1、S2And S3In have one or two controlling switch (2) all the time in opening, in addition two
An individual or controlling switch (2) is closed, and null vector does not have any influence on vector operation result, therefore, under
No longer be referred to as during the literary vector non-vanishing vector and two null vector vectors and/or two non-vanishing vectors and one zero to
Amount vector, but it is referred to as three vectorial vectors.
