In beam theory, it is assumed that the planar cross-section of the beam remains planar and remains perpendicular to the axis of the beam as it bends. This implies that two material lines, the axis of the beam and a material line in the plane of the cross-section, remain perpendicular to each other. In view of this assumption, what is the transverse shear strain along the axis of the beam

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

Select any two (2) areas of applications of chain-drive. (clo4) a)-permanent lubrication necessary b)-hydraulic forklift truck operation c)-rigging and heavy moving materials d)-relatively high maintenance costs e)-costlier than belt drives

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
