An electric kitchen range has a total wall area of 1.40 m2 and is insulted with a layer of fiber glass that has a temperature of 175oC and its outside surface is 35 oC. The
fiber glass has a thermal conductivity of 0.040 Wm-1K-1
. Calculate the rate of flow of
heat through the insulation, assuming the fibre as a flat slab of area of 1.40 m2
.

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.
