Determine the tensions developed in wires , and and the angle required for equilibrium of the 30-lb cylinder E and the 60-lb cylinder F.
Two tow trucks lift a 100 lb motorcycle out of a ravine following an accident. If the motorcycle is in equilibrium in the position shown, what are the tensions in cables AB and AC?
Finding exit velocity from air nozzle, Air enters a nozzle operating at steady state at 800 ºR with a negligible velocity and exits the nozzle at 570 ºR.
Important information about Multipal choice question on mechanics, A machine is supplied energy at a rate of 4,000 W and does useful work at a rate of 3,760 W. What is the efficiency of the machine?

Probabilistic Hough transform in big O notation
calculate the vapor pressure-temperature relationship of liquid iron.
Assuming that the bomb is perfectly insulated what is the temperature of the air in the bomb at the end of filling process? Assume air is an ideal gas with constant specific heats in a ratio Cp/Cv = γ = 1.4 and constant R= 287 J/kg K.
determine (a) the compression ratio, (b) the cycle efficiency, (c) exhaust temperature, and (d) mean effective pressure (kPa). Draw (e) a P-v diagram and (f) a T-s diagram
A 50 hp motor with an efficiency of 0.80 is to be replaced by a newer model motor with an efficiency of 0.90. The motor is expected to operate 3000 hours per year. The cost of electricity in our area is $0.06 per kWhr.
The two mooring cables exert forces on the stern of a ship. Represent each force as a Cartesian vector and determine the magnitude and direction of the resultant.
A piston-cylinder device initially contains 50L of liquid water at 40 degrees C and 200kPa. Heat is transferred to the water at constant pressure until entire liquid is vaporized.
Steam enters a turbine operating at steady-state at 700 ºF and 600 lbf/in2 and leaves at 0.6 lbf/in2 with a quality of 90%. The turbine develops 12,000 hp
