he simply supported beam consists of a W21 × 44 structural steel wide-flange shape [E = 29,000 ksi; I = 843 in.4]. Assume that the support at D can exert a downward force to maintain equilibirium (contrary to the way it is drawn). Assume L1 = 11 ft, L2 = 8 ft, and L3 = 4 ft. For a loading of w = 5 kips/ft, determine: (a) the beam deflection at point C. (b) the beam deflection at point E.

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct
