Select the correct answer
a civil engineer is performing a tensile test on a brick. immediately after he adds the first weight, the brick splits into two parts why did this happen?
o a.
brick has high elastic moduli
ob. brick has low tensile strength
oc.
compressive stress on the brick
od. shear stress on the brick
o e
torsion stress on the brick

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.
