Consider two bars of equal length but different material suspended from common support as shown. If we knew nothing about the bars except that they could support the indicated axial loads [500 N for bar A and 5000 N for bar B], which material do you think is stronger? Bar A or Bar B? *

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa.s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false

For a process taking place in a closed system containing gas, the volume and pressure relationship is pvi-constant. -1.5 bar, the process starts with initial conditions, pi = =0.03 m3 and ends with final volume, v2-0.05 m3 determine the work done by the gas.
