The rigid beam of negligible weight is supported horizontally by two springs and a pin. if the springs are uncompressed when the load is removed, compute the vertical force at end c when the load is applied and the beam is in horizontal position. assume the spring stiffness k is large enough so that only small deflections occur. (hint: the beam rotates about a so the deflections in the springs can be related)

Avehicle has an oil leak that is causing the entire oil pan to be wet, but inspection reveals no exact source after cleaning off the oil residue. technician a says to install a fluorescent dye in the crankcase and operate the engine, then re-inspect for leaks with a special light (black light). technician b says the oil leak may be coming from a source at the top of the engine, such as a valve cover gasket. who is correct?

Which statement best describes the superposition principle? a.) if two in-phase waves arrive simultaneously at a point, their amplitudes add up b.) if two out-of-phase waves arrive simultaneously at a point, their amplitudes add up c.) if two in-phase waves arrive at a point one after another, their amplitudes add up d.) if two out-of-phase waves arrive at a point one after another, their amplitudes adds up
