doubtless is the available crushingstrength of this specimen, it may by no means represent the maxi-mum resistance to crushing under other conditions. i6 STRUCTURAL MECHANICS. If pi=P+S is the unit thrust on the right section, it is seen,from § 151, that, on a plane making an angle 6 with the… … Fig. 2 to sliding along this oblique plane will be mpn = mp\ cos2 6, andthe portion of the unit shearing stress tending to produce fracturealong this plane will be q — mpn = pi (sin 6 cos 0 — m cos2 0). Fracture by shearing, if it occurs, will take place along thatplane for which the above…
