Astrain gauge rosette is applied to a structure which is then loaded. one of the gauges, a, which is aligned in a reference, x, direction records a strain of 400 he when the structure is loaded. the other two gauges, b and c, which are positioned at 45° and 75° counterclockwise to the first gauge simultaneously record strains of 150με and 50με respectively. using the strain transformation equations determine the values of the principal strains at the point in the structure where the gauges are located. assuming that a state of plane stress exists within the structure determine the corresponding values of the maximum principal stress at this point. take young's modulus as 70gpa and poisson's ratio as 0.25.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
