Q. The decibel level of the noise from a jet aircraft is 130 dB when measured 15.3 m from the aircraft.
(a) How much sound power does the jet aircraft emit?
(b) How much sound power would strike the eardrum of an airport worker 15.3 m from the aircraft? (Use 1.9 10-2 m as the diameter of the ear.)
The drawing shows an edge-on view of two planar surfaces that intersect and are mutually perpendicular. Surface 1 has an area of 2.2 m2, while surface 2 has an area of 3.5 m2.
Rank the vector combinations on the basis of their angle, measured counter clockwise from the positive x axis. Vectors parallel to the positive x axis have the angle of 0. All angle measures fall between 0 and 360.
The coefficient of static friction between the wall and the rod is μs = 0.575. Determine the minimum distance x from point A at which an additional weight w (the same as the weight of the rod) can be hung without causing the rod to slip at point A.
A sanding disk with rotational inertia 8.1 x 10-3 kg·m2 is attached to an electric drill whose motor delivers a torque of magnitude 20N·m about central axis of the disk. About that axis and with torque applied for 29 ms, what is the magnitude of (..
