Acantilever of 3 m length with a t-shaped cross-section is loaded by three concentrated loads: w,-80 n at the free end, w 30 n, and w,-60 n at a distance of 1 m from the free end. all loads are applied at the outer edges of the flange as indicated in the sketch below. (a)-determine the maximum torsional shear stresses in the flange and in the web at distances 0.5 m and 2.5 m from the free end (sections i and ii marked in the sketch) b)- determine thefh end cross section assuming a shear modulus of 210 gpa.

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.

Air is compressed isentropically from an initial state of 300 k and 101 kpa to a final temperature of 1000 k. determine the final pressure using the following approaches: (a) approximate analysis (using properties at the average temperature) (b) exact analysis

A)-in the process of engineering design, explain the contribution of material selection. b)- explain the procedure of synthesis as is employed in engineering design. c)- is there any relationship between ergonomics and engineering design? explain. d)- safety consideration in engineering design includes human, product and the enviroment . explain how safety will be incorporated into the design?
