Asimply supported 25-foot long w33x141 beam (fy = 50ksi) supports a uniformly distributed service load. if the live load is twice the dead load, what is the maximum total service load that can be supported. don’t forget to factor in self weight. you can assume that the beam is compact and that it has continuous lateral support.

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.
