The space truss shown is supported by a ball-and-socket joint at D and by short links at A and C. Determine the support reactions and the force in each member of the space truss.
if point D is at (100,100) and the line DE to "E" is 300 feet long at an azimuth of 225 degree , what is location of point E in the XY coordinate system. what is the length and azimuth of the line connection points (100,100) to (300,500)
Consider CO2 emissions from a gasoline powered vehicle. Gasoline is acomplex mixture of hydrocarbons but for the purposes of this calculation assume an average molecular formula of C7H16.
What is the maximum safe speed around the curve? If the speed limit on the roadway is 60mph, what action should be taken by the engineer?
A soil has a moisture content of 31.4%, a degree of saturation of 90% and a unit weight of 17.3kN/m^3. Determine the specific gravity of the soil solids.
Knowing that portion AC of the rope lies in a plane parallel to the xy plane and that the magnitude of the tension T in the rope is 62 lb, determine the moment about O of the resultant force exerted on the pulley by the rope.
Fluids A and B ave specific gravities .75 and 1.00 respectively. If the mercury is used as manometer liquid determine the pressure difference between A and B
