Lorentz-FitzGerald contraction The Irish physicist G.F. FitzGerald and the Dutch physicist H.A. Lorentz tried to account for the null result of the Michelson- Morley experiment by the conjecture that movement through the ether sets up a strain that causes contraction along the line of motion by the factor 1 - 1 2 v2/c2. Show that this hypothesis can account for the absence of fringe shift in the Michelson-Morley experiment. (The hypothesis was disproved in 1932 by experimenters who used an interferometer with unequal arms.)
consider a circular grill whose diameter is 0.6m. the bottom of the grill is covered with hot coals at 1000k. a wire
A three-point bending test is conducted on an aluminium oxide ceramic with a circular cross section. The ceramic has a radius of 4 mm. The specimen fractures at a load of 1100 N as measured by an Instron universal tester. If the distance between the ..
Find the dynamic load on each bearing due to out of balance couple. The distance between each eccentric is 8 cm from the centre of the shaft where the second eccentric is fixed.
Pinch analysis (or pinch technology) is a popular methodology for optimizing the design of heat exchanger networks in complex thermal systems. Pinch analysis uses a primarily graphical approach to implement second-law reasoning.
the virial equation of state for n-butane at 460k is z1avbv2 in which a -265 cm3g and b 30250 cm6gmole2. calculate the
Write a MATLAB program that takes an input of the stress state in 3D. The program should Create the stress tensor. Calculate the principal normal and shear stresses by solving the eigen value problem.
an engineering student measures an ambient lab pressure and temperature of 405.35 in. h2o and 70.5 f respectively and
The length of dislocation line per unit volume in a material equals the number of dislocations per unit area. Metals are hardened by cold working because many of the dislocations have passed right through the grains and are no longer available to fac..
a cylindrical storage tank with dimensions of 15 m height and 15 m inside diameter is used to store oil having a
Friction between the piston and cylinder wall can be neglected because the process occurs so slowly. For the air, determine the initial and final pressures in kPa and the boundary work for the process in kJ.
some unknown volume of oil sg 0.918 has been dumped into a vat of sea water sg 1.028 forming a stratified layered
a gas is contained in a vertical frictionless piston cylinder device. the piston has a mass of 4 kg and crosssectional
