Member abcd (the focus of this problem) is supported by a collar at d that can rotate and slide along bar ef, which is fixed and frictionless. structure abcd makes contact with smooth surfaces at a and c where the normal direction n to the surface at alies in a plane that is parallel to the xy-plane. force p is parallel to the y-axis. if p = 10 kn, determine the reactions at a, c and d.

Consider a 1.2 meter high and 2 meter wide glass window whose thickness is 6 mm and thermal conductivity is 0.78 w/m °c. the room temperature is maintained at 24 °c, while the outdoor temperature is -5 °c. the convective heat transfer coefficients on the inner and outer surfaces of the window are 10 w/m2 °c and 25 w/m2 °c respectively. (a) draw the thermal resistance network, etermine the steady rate of heat transfer t e glass window (c) determine the temperature of the inner surface of the window
