Afour-stroke cycle engine delivers a torque of 437 ft-lb at the flywheel (output shaft) when the engine speed is 2100 rpm while using 514 hp of fuel equivalent power. this six-cylinder engine has cylinders with a bore of 4.19 in, a stroke of 5.0 in, and a clearance volume of 8.81 in^3. a. what is the brake power (hp) delivered by this engine? b. what is the brake mean effective pressure (lb/in2) for this engine? c. what is the brake thermal efficiency of this engine?

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.
