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), M_p 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

1. An aluminum air-cooled engine cylinder head for a single cylinder, 2-stroke engine is to be die-cast. The overall diameter of the cylinder head is 101.6 mm. If the projected plan area of the runners and gating system is 100 mm2 and the casting pressure is 10 MPa (1500 psi), what minimum locking force is required for the die-casting machine in kN.

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...

Assume that a single cylinder of an automobile engine has a volume of 523 cm3 . a. If the cylinder is full of air at 77 ∘C and 0.980 atm , how many moles of O2 are present? (The mole fraction of O2 in dry air is 0.2095.) b. How many grams of C8H18 could be combusted by this quantity of O2, assuming complete combustion with formation of CO2 and H2O?

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?
