The "flying car" is a ride at an amusement park which consists of a car having wheels that roll along a track mounted inside a rotating drum. By design the car cannot fall off the track, however motion of the car is developed by applying the car's brake, thereby gripping the car to the track and allowing it to move with a constant speed of the track, vt = 3 m>s. If the rider applies the brake when going from B to A and then releases it at the top of the drum, A, so that the car coasts freely down along the track to B (u = p rad), determine the speed of the car at B and the normal reaction which the drum exerts on the car at B. Neglect friction during the motion from A to B. The rider and car have a total mass of 250 kg and the center of mass of the car and rider moves along a circular path having a radius of 8 m.
A damped system is driven by a harmonic force F(t)=18 sin(12t). The system has a mass of 17.5 kg and damping constant of 42 N/s/m. Determine the spring constant k which produces maximum amplitude response. Also find out the maximum amplitude; (b) If ..
A piston-cylinder assembly contains a two-phase liquid-vapor mixture of H2O at 200 lbf/in^2 with a quality of 80%. The mixture is heated and expands at constant pressure until a final temperature of 480 F is reached. Determine the work for the proces..
a gas that is contained in a cylinder undergoes two processes that are in series. the first process from 1 to 2 consist
A new motorcycle is being developed to meet new gas mileage standards recently passed by the federal government. An engineer tested three model designs by randomly assigning the motorcycles in a blind study (the riders recorded the mileage but did no..
Typical towns in states with big plains like Texas need an elevated tank to supply tap water. Below there is a picture of a typical elevated tank. If we approximate the tank as a cylinder with a diameter of 50 ft and a height of 25 ft, answer the fol..

Assume they test null hypothesis H0: versus H1: Will the engineers decide to use the steel if H0 is rejected? Will the engineers decide to use the steel if H0 is not rejected?
consider a 1-cm-diameter and 0.3-m-long copper rod kcopper 400 wm-k with its ends fixed to two parallel surfaces. the
An Ocean Thermal Energy Conversion (OTEC) power plant built in Hawaii in 1987 was designed to operate between the temperature limits of 86°F at the ocean surface and 41°F at a depth of 2100 ft. About 13,300 gpm of cold seawater was to be pumped from ..
Determine the maximum speed at which the car with mass can pass over the top point A of the vertical curved road and still maintain contact with the road.
