A60-lb uniform thin panel is placed in a truck with end a resting on a rough horizontal surface and end b supported by a smooth vertical surface.

knowing that the deceleration of the truck is 12-ft/s2 , determine :

(a) the reactions at ends a and b

b) the minimum required coefficient of static friction at end a.

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

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
