Communication satellites are placed in a geosynchronous orbit,that is, in a circular orbit such that they complete one full revolution about the earth in one sidereal day (23.934 h), and thus appear stationary with respect to the ground. Determine (a) the altitude of these satellites above the surface of the earth, (b) the velocity with which they describe their orbit. Give the answers in both SI and U.S. customary units.
Calculate the angular separation between the first order minima on either side of the central maxima when the slit has a width of 6x10-4 cm & light illuminating it has a wavelength of 6000A0?
Plot the moment about B for 320mm
Evaluate the variation of hoop stresses across the wall of the compound cylinder.
The link BD is a single solid bar with a width x thickness measuring 1.000 in. x 0.50 in. If the pins at A, B and D have a diameter of 0.375 in, determine the average normal stress in link BD when:(b) Fx = 0 and Fy =4.00 kips.
Determine the analytical solution for the maximum stress of the beam shown; compare with stress results from SolidWorks.
What is the advantage of sketching an object first before drawing it using CAD?
a ball is shot vertically into the air 50 m/s 108m from the ground. 6 seconds later, another ball is shot vertically into the air 20 m/s 58m from the ground. Find the distance where they meet in the air from the ground.
Determine the normal force R between the wheel and the horizontal surface. Neglect the weight of the horizontal shaft.
use potential flow theory to determine the lift coefficient of a spinning baseball in terms of the forward velocity v
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.
