HELP TIMED 2 MIN LEFT Explain what Sam can do to fix his engine in the following scenario.

Situation: Sam tried out a new hobby and rebuilt a car from scratch. When he got to the crankshaft, he was careful to attach it to the camshaft with the gears. He also made sure that the pistons were tightly attached to the crankshaft gears as well. It was also held in place by a series of journals. Finally, he made sure that the belt was in place on one side of the crankshaft. When James came over to look at the car, he noticed that Sam's crankshaft was still incomplete.

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.

For the closed feedwater heater below, feedwater enters state 3 at a pressure of 2000 psia and temperature of 420 °f at a rate of ix10 ibhr. the feedwat extracted steam enters state 1 at a pressure of 1000 psia and enthalpy of 1500 btu/lbm. the extracted er leaves at an enthalpy of 528.7 btu/lbm steam leaves as a saturated liquid. (16) a) determine the mass flow rate of the extraction steam used to heat the feedwater (10) b) determine the terminal temperature difference of the closed feedwater heater
