For the pendulum shown in the figure,the restoring torque due to gravity is given by T=mgLsin(thita). Derive the linearised equation about the operation point thita=0.
Solve for the dynamics of the resulting system for 20 seconds of real time using midpoint method.
A turbine salesman makes the following claim for one of his products: Steam enters a steady-flow adiabatic turbine at 4 MPa, 600 °C with negligible velocity and exhausts at 200 kPa with a velocity of 180 m/s
A wheel barrow is used to lift a 200 lb load. The length from the wheel axle to the center of the load is 2 ft. The length from the wheel and axle to the effort is 5 ft. 5. What is the ideal mechanical advantage of the system?
Midrange and amplitude components, A shaft is subjected to a completely reversed bending stress such that Xmax=40kpsi and Xmin=-40kpsi
A compressor operating adiabatically is to compress 2.83 m^3/min of air at 29.4C and 102.7 kN/m^2 to 311.6kN/m^2. Calculate the power required if the efficiency of the compressor is 75%. Also, calculate the outlet temperature.
The steam from the nozzles of a single wheel impulse turbine discharges with a velocity of 600 m/s at an angle of 20 degrees. The blade wheel rotates at 3000 rev/min and the mean blade radius is 590 mm
which of these two processes will produce the largest amount of work? (You must provide a full explanation for your choice).
Calculating a Constant Pressure Process, In a constant pressure, nonflow process, 6Btus of heat are added to a gas while the volumes change from 1.6ft^3 to 2.0ft^3
A launch approaches a wharf at a speed of 10.5 knots(=5.4m/s).The engine are put in the reverse when the launch is 10 m from the wharf, the retardation being 1.25m/s squared. will the launch come to rest before hitting the wharf.. If not, with wha..
calculate the enthalpy change of the universe during the process. Cp=Cv = 4.18 kj/kgK
Block A has a mass of 3 kg and B has a mass of 5 kg. If the system is released from rest, determine the velocity of each block in t=4s. Neglect the mass of the pulleys.
260-pound weight is supported by two ropes, one forming a 40 degree angle with the ceiling and the other a 50 degree. Find the tension in each rope.
