Question: The cylinder shown in Figure P5.108 has mass M and radius r and rolls without slipping on the horizontal plane. At O, it is connected via a frictionless joint to bar OA, having mass m and length l. The right end of the bar is connected to point B by an inextensible cord of length l and negligible mass.
Tasks: (a) Select coordinates and state the required kinematic-constraint equations.
(b) Draw the required free-body diagrams for the two bodies and develop the governing equations of motion.
(c) State the governing equations for unknowns in matrix format.

Steam at 3MPa and 400C enters an adiabatic nozzle steadily with a velocity of 40m/s and leaves at 2.5MPa and 300m/s. Determine the exit temperature in degrees C. the ratio of the inlet to exit area
what is second-law efficiency for the combined system?
Consider a system with loop transfer function: GH(s) = (s(s + 2))/(s + 1)(s2 + 1). Sketch the Nyquist curve for this loop transfer function and using the Nyquist stability criterion determine the stability of the closed-loop system.
Obtain a close approximation to the impact velocity v from the data given
Water in the pictured piston cylinder assembly has an initial quality of 10%. The piston cylinder is 20 cm in width and the piston is initially 40 cm high. Heat is added until the temperature of the steam reaches 500°C. While heat is being added the ..
Water is boiled at sea level (1 atm pressure) in a pan placed on top of a 2-kW electric burner that transfers 60% of the heat generated to the water. Determine the rate of evaporation of water in kg/s.
