Amilling operation was used to remove a portion of a solid bar of square cross section. if a = 30 mm, d = 20 mm, and σall = 60 mpa, determine (a) the magnitude p of the largest forces that can be safely applied at the center of the ends of the bar if the stress concentration at the fillet is ignored, and (b) the max value of p if the stress concentration is considered (idealize your section with d=d and pretend fig 4.24 of b& j applies when estimating k).

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.

Manometers are good examples of measuring instruments, nowadays they are not as common as before. a)-capacitive probe gauges b)-gravitational gauges deformation ) gauges d)-digital gauges
