When the soil reaches the limit equilibrium state, the location of shear failure surface must be on the maximum shear stress surface（ ）

A metal surface illuminated by 8.5×1014 Hz light emits electrons whose maximum energy is 0.52 eV. The same surface illuminated by 12.0×1014 Hz light emits electrons whose maximum energy is 1.97 eV. The work function of the metal is (  B )

A floating<br/>lookback call option pays off which of the following ( ) A: The amount by<br/>which the final stock price exceeds the minimum stock price B: The amount by<br/>which the maximum stock price exceeds the final stock price C: The amount by<br/>which the strike price exceeds the minimum stock price D: The amount by<br/>which the maximum stock price exceeds the strike price

Obtain numerical values for the maximum tensile stress (\(\sigma^+_\max\), in MPa) in the beam, and for the coordinates (\( x_\max,\ y_\max, \) in m) where \( \sigma^+_\max \) occurs:<br/>\&#91; y_\max = \&#93;<br/>\&#91; x_\max = \&#93;<br/>\&#91; \sigma^+_\max = \&#93;<br/>______

Due to the pure bending deformation, the longitudinal ( ) strain varies ( ) from ( ) at the neutral axis to a maximum at the outer fibers of the beam. A: normal; linearly; zero B: shear; nonlinearly; zero C: shear; nonlinearly; zero D: shear; nonlinearly; zero
