P8.045 go multipart part 1 correct answer. correct an aluminum [e = 1 ksi] bar is bonded to a steel [e = 3 ksi] bar to form a composite beam. the aluminum bar has width b = 2.50 in. and height d1 = 0.500 in. the steel bar has width b = 2.50 in. and height d2 = 0.875 in. the composite beam is subjected to a bending moment of m = +150 lb-ft about the z axis. determine: (a) the maximum bending stresses in the aluminum and steel bars. (b) the stress in the two materials at the joint where they are bonded together. transform the steel bar (2) into an equivalent amount of aluminum (1). calculate the transformed width for the steel bar b2,trans.

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.
