Knowing that the cylinder rolls without sliding on the carriage and neglecting the mass of the wheels of the carriage, determine the resulting velocity of (a) the carriage, (b) the center of the cyl
Steam is supplied to a two stage turbine at 40 bar and 350 C. It expands in the first turbine until it is just dry saturated,then it is re-heated to 350 C and expanded through second-stage turbine.
A steel disc 300 mm diameter of mass 29kg, is suspended from the end of a wire 2.5 mm diameter and 1.5 m long which is clamped into a central hole in the disc.
The turbine rotor in the power plant of a ship as shown in Fig. 3 has a weight of 12.75 kN with centre of gravity at G and has a radius of gyration 200 mm. The rotor is mounted in bearings A and B w
Determine the maximum load that can be applied for the plate not to fail by yielding or fracture (rapid crack extension). Assume the correction parameter for stress intensity factor to be 1.
A solo motor cycle, ride and passenger together have a mass of 320 kg, the combined centre of gravity being 525mm above ground level. The wheels of the machine each have a mass of 9 kg, a radius of

A cylindrical component made from S-590 alloy has a diameter of 20 mm. Determine maximum load that may be applied for it to survive 1000 hours at 9250 C?
Car A starts from rest at t=0 and travels along a straight road with constant accelaration 2m/s2 until it reaches a speed of 27 m/s. Afterwards it maintains this speed.
The eccentricity is 0.1, the inclination is 30 degree and the argument of periapsis is 60 degree. Calculate the single delta v required at C for this maneuver, in terms of v0.
A steam turbine operates with 1.6 MPa and 350 degree C steam at its inlet and saturated vapor at 30 degree C at its exit. Determine the heat loss rate through the turbine casing when the mass flow
The free convection heat transfer coefficient on a thin hot vertical plate suspended in still air can be determined from observations of the change in plate temperature with time as it cools.
Two structural members, A and B are riveted to a bracket. Angle iron A is at 20 deg fro perpendicular with a compression force at 1600 lbs and angle iron B is at 45 deg to perpendicular and under 12
If the management decided to use the standard hour plan as an incentive system, find the standard hour rate to be used in the calculation of the payments to the workers?
In a mechanical coal-washing process, a portion of the inorganic sulfur and ash material in the mined coal can be removed. A feed stream to the process consists of 73% coal, 11% ash, 11% sulfur, and
A pipeline has been proposed to carry natural gas 1715 miles fro Alaska's North Slope to Calgary, Alberta, Canada. The (smooth) pipe diameter will be 52 inches. The gas will be at high pressure, ave
