consider uniform potential flow past an ellipse with thickness ratio T. Use an appropriate joukowski transformation to find the complex potential for the flow around the ellipse in terms of its geometrical parameters. Use thin airfoil theory to show that the pressure coefficient across the length of the ellipse in the stream-wise direction is constant when it is assumed T<<1.
If the trap door's weight is 50N. Calculate the tension in the string and the reaction at the hinge.
determine diameter of a circular rod of ductile material with a fatigue strength ,e=280 Mpa. Add a tensile yield strength of 350 Mpa. The member is subjected to a varying axial load from 700 kN to -300kN. Assume Kt=1.8 and factor of safety=2.
determine the force exerted by each cylinder in raising the crate for u = 60°, a 5 0.70 m, and L = 3.20 m. Show that the result obtained is independent of the distance d.
The compression ratio of an air-standard Otto cycle is 9.5. Prior to the isentropic compression process, the air is at 100 kPa, 17 C, and 600 cm2
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.
Given a simulator or actual device, identify if a control loop is in control or out of control and identify the information used to make the decision
Use the bisection method to determine the drag coefficient (cd) needed so that a 80 kg bunjee jumper has a velocity of 36 m/s after 4 s of free fall.
Two bars, one having a circular section of radius b, the other an elliptic section with semiaxes a,b. For equal angles of twist, which bar experiences the larger shearing stress?
A vehicle of mass 1500kg and track 1.8m has a centre of mass located centrally at 1,1m above the ground. It has to travel around a bend of 56m radius to the centre of mass.
Use steam tables to compute the total volume, total enthalpy, and total entropy of 1kg of water at 100o C, half by weight of which is steam and the remainder is liquid water.
What is a beam? What factors determine the maximum load that it can take without failure?
A long electric wire of radius r0 generates heat at rate of q'''. The surface is maintained at uniform temp of T0. Write heat equation and boundary conditions for steady state one dimensional conduction.
