Find the internal torques for segments AB, BC, and CD (in N-m) by drawing the internal torque diagram, the maximum torsional shear on the shaft in MPa, and the relative rotation of section A with respect to section D in degrees.
Determine the heel and toe stresses and the factor of safeties for sliding and overturning for the gravity dam section shown in the figure below for the following loading conditions: - Horizontal earthquake (Kh) = 0.1 - Normal uplift pressure with gallery drain working Silt deposit up to 30 m height - No wave pressure and no ice pressure Unit weight of concrete = 2.4 Ton/m³ and unit weight of silty water = 1.4 Ton/m³ - Submerged weight of silt = 0.9 Ton/m³ == - Coefficient of friction = 0.65 and angle of repose = 25° Solve this question with the presence of gallery and without gallery., discuss the issue in both cases....

The efficiency for a steel specimen immersed in a phosphating tank is the weight of the phosphate coating divided by the metal loss (both in mg/ft²). An article gave the accompanying data on tank temperature (x) and efficiency ratio (y).
