Consider a circular cylinder which is pressed 'end on' against a flat surface of the same material.
(a) Find an equivalent geometry of a cracked body where the asymptotic crack-tip fields are the same as those around the contact zone boundary between the cylinder and the flat surface.
(b) Determine the distribution of crack-tip fields using fracture mechanics solutions and compare them with the solutions given in any monograph on contact mechanics. Show that they are equal in the asymptotic limit.
Write a balanced net equation for the reaction of the hydrogen ascorbate anion with water where hydrogen ascorbate acts as an acid.
1 discuss the different agencies institutes centers and other national bodies that are involved in environmental work
A pump is necessary to lift water from the clear well (reservoir) at a water treatment plant to a storage tower 50-ft high and some distance away. A flow rate of 15 cubic per second (cfs) is required (68F).
A motorcycle starts from rest at t = 0 and travels along a straight road with a constant acceleration of 4ft/s^2 until it reaches a speed of 50ft/s . Afterwards it maintains this speed. Also, when t = 0, a car located 8000ft down the road is travelin..
The sum of the mole fractions for an ideal-gas mixture is equal to 1. Is this also true for a real-gas mixture?
Water flows from a ground storage tank that is 450 feet above a town's water distribution system. The pressure at the entrance of the system must be at least 75 psi and the demand is 1350 GPM.
A bridge having a horizontal top cord is span between tow piers Aand B having an arbitrary height. It is required that apin-connected truss be used, consisting of steel members boltedtogether to steel gusset plates. The end supports are assumed to be..
At a given point on a horizontal streamline in flowing air, thestatic pressure is -2 psi (ie vacuum) and velocity is 150 ft/s.Determine the pressure at a stagnation point on thatstreamline?
A 440 -V shunt motor has armature resistance of 0.8 ohm and field resistance of 200 ohm . determine the back emf when giving an output of 7.64 KW at 85% efficiency
The frame ACD is supported by ball-and-socket joints at A and D. The blue cable passes smoothly through the ring at B. If you assume the frame is weightless and P = 75 lbs. what is the tension in the cable?
You must submit a valid design to me before you will receive your building materials. I will not grade your design based on whether it will support the necessary load. I am only approving it as to whether it is a design that meets the building req..
If the pulleys are fixed to the shaft, determine the magnitude of the tension T and the x,y,z componenet sof reaction at the smooth thrust bearing A and smooth journal bearing B.
