A classical synchronization problem is an analogy of a single-lane tunnel, also known as the single-lane east-west bridge. To avoid a deadlock, cars must be prevented from entering the tunnel at both ends simultaneously. Once a car enters, other cars from the same direction may follow immediately.(a)Ignoring the problem of starvation, solve the problem using semaphores. Hint: The tunnel problem is a variation of the readers/writers problem where multiple readers or multiple writers are allowed to enter the critical region.

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

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.
