अवधारणा:

सक्रिय भू-दाब गुणांक:

\({C_a} = \frac{{1 - \sin \left( \phi \right)}}{{1 + \sin \left( \phi \right)}} = {\tan ^2}\left( {45 - \frac{\phi }{2}} \right)\;\)

निष्क्रिय भू-दाब गुणांक:

\({C_p} = \frac{{1 + \sin \left( \phi \right)}}{{1 - \sin \left( \phi \right)}} = {\tan ^2}\left( {45 + \frac{\phi }{2}} \right)\;\)

याद रखने योग्य बिंदु:

शियरिंग कोण के किसी भी मान के लिए, सक्रिय भू-दाब गुणांक और निष्क्रिय भू-दाब गुणांक का गुणनफल हमेशा 1 के बराबर होगा।

\({C_a} \times {C_p} = \frac{{1 - \sin \left( \phi \right)}}{{1 + \sin \left( \phi \right)}} \times \frac{{1 + \sin \left( \phi \right)}}{{1 - \sin \left( \phi \right)}} = 1\)
