An emergency patient is being seen today because of a lost "filling.” The dentist examines tooth #5 and requests that a radiograph be taken and schedules the patient for a new
restoration. The dentist asks you to place a temporary restoration until the patient can come
back for a scheduled appointment. Which temporary dental material would most likely be
used to replace the lost filling?

An engine, weighing 3000 n, is supported on a pedestal mount. it has been observed that the engine induces vibration into the surrounding area through its pedestal at the maximum operating speed. determine the stiffness of the dynamic vibration absorber spring in (n/m) that will reduce the vibration when mounted on the pedestal. the magnitude of the exciting force is 250 n, and the amplitude of motion of the auxiliary mass is to be limited to 2 mm note: in this question type-in right numbers, no decimals, no fractions, no unit. approximate to right number if needed
