MECHANICAL ADVANTAGE & EFFICIENCY: In this problem Carlitos is pushing a 50 pound drum up a ramp (inclined plane). He is pushing with
22 pounds of force. The ramp is 12 feet long and the dock at the top of
the ramp is 3 feet high. When solving, always write out all calculations and
report your answers by uploading a picture of all your work (that you did
on a blank sheet of paper). Find the AMA, IMA, and efficiency.

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct

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.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false
