In fracas failure trend analysis, match these findings with their probable root cause (some may be used more than once, and some may not be used): different components from the same vendor fail in different applications. design issue. b. manufacturing workmanship or process issue. isame component, possibly from different vendors, fails, but in the same location (on a circuit card, for example). c. wearout issue a component seems to fail, but when the component is removed and tested, it tests ok dvendor process or vendor quality issue. failure only happens during certain conditions (such as environmental)

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.

Manometers are good examples of measuring instruments, nowadays they are not as common as before. a)-capacitive probe gauges b)-gravitational gauges deformation ) gauges d)-digital gauges

Select any two (2) areas of applications of chain-drive. (clo4) a)-permanent lubrication necessary b)-hydraulic forklift truck operation c)-rigging and heavy moving materials d)-relatively high maintenance costs e)-costlier than belt drives
