The rigid beam is supported by the three suspender bars. bars ab and ef are made of aluminum and bar cd is of aluminum and bar cd is made of steel. if each bar has a cross-sectional area of 450 mm2 determine the maximum value of p if the allowable stress is (o-allow) sit_200 mpa for the steel and (sigma_ailow)a| = 150 mpa for the aluminum. e_st = 200 gpa, e_al = 70 gpa.

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

Ifa component is made of two or more materials with different modulus of elasticity (e), it is called a composite member and we calculate the factor·n". mention the formula for calculating n". also, ifn> 1, explain what will happen to the 1. transformed.gi) ifn 1, what will happen to the material when transformed material when

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.
