A steel shaft ABCD having a total length of 3 m consists of the following different sections:
AB is hollow having outside and inside diameters of 10 cm and 6.25 cm, respectively, and BC and CD are solid, BC having a diameter of 10 cm and CD a diameter of 8.75 cm.
Find the safe applied torque that can be transmitted by the shaft ABCD, if the maximum shear stress in the hollow section is 47 MPa and G = 82.5 GPa.
If the angle of twist is the same for each portion, determine the length of each section.
Determine the reactions of simply supported beam to both a concentrated and uniform load. A beam with a span of 21 ft is simply supported at the left-hand end and fixed at the right-hand end.
Determine the thermal efficiency of the cycle and the net specific work. Assume each turbine stage isentropic efficiency to be 99% and assume the FWH is open.
Apparent Density, Theoretical Density and Void Volume, A compacted body of iron powder is sintered into a 20mm-diameter, 45-mm-tall cylinder which, upon weighing
The purpose of this project is to introduce you to the application of FEA by using the ANSYS software to examine the deflection of an I-beam under a point load.
Determine the heat transfer coefficient for laminar flow over this cylinder. First, at your discretion, select an available set of experimentally obtained data from the literature. Then, this would provide you with a set of Reynolds numbers.
Questions set on Entropy, Exergy, Cycles, Otto Cycle, Rankine Cycle. In a coal fired thermal power station, indicate where the exergy contained in the coal is destroyed. For each exergy destruction mechanism, explain whether there is a small..
Evaluate the valve closure to achieve a water exit velocity
Equation of an elastic curve, Given the equation of the elastic curve for a simply supported beam, how would you obtain the slope in the beam, since the equations are related?
