A civil engineer is performing a tensile test on a brick using a tension machine. Immediately after he adds the first weight, the brick splits into two parts. Why does this happen? A. high elastic modulus of brick B. low tensile strength of brick C. compressive stress on the brick D. shear stress on the brick E. torsion stress on the brick

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false
