mechanical vibration

Consider a single cylinder engine such as the one shown here where r is the radius of crank (5.0 cm), l is the length of the connecting rod (16 cm), Mp is the effective mass of piston (1.5 kg), M is total mass of engine (75 kg), w is the engine speed (24p rad/s), k is the spring constant (220 KN/m), and z is the damping ratio (0.02). Assume that the crank and the remaining portion of the connecting-rod mass, which is considered concentrated at the crankpin, is balanced so that its center of gravity is at the axis of rotation O; determine

Equation of motion for the system

Exciting force of the engine and plot it for 30 seconds using 600 equal time intervals.

Absolute maximum steady-state amplitude of the engine

Plot the steady state time responses for the displacement and velocity of the engine for 30 seconds using 600 equal time intervals.

Consider a cylinder of radius R = 1000 km and, for our purposes here, infinite length. Let it rotate about its axis with an angular velocity of Ω = 0.18◦/s. It completes one revolution every 2000 s. This rotation rate leads to an apparent centrifugal acceleration for objects on the interior surface of Ω2 R equal to 1 g. Imagine several competing teams living on the interior of the cylinder, throwing water balloons at each other. (a) Show that when...

In an engine cycle like the one shown in Figure
In an engine cycle like the one shown in Figure    heat is added over a range of temperatures. Explain why even if it were run reversibly, its efficiency would be less than the Carnot limit defined by the high- and low-temperature set points and shown in the figure ( ηC = T4-T2)/T4. Is this in itself a disadvantage of such a cycle?
