If we have the satellite state vector and the station coordinates and the modified julian date, how can we find topocentric right ascension and declination, azimuth and elevation.

What is the name for the type of motor used to drive CNC axes that is also capable of recording axis position?

The line type used to show edges of an object that can be seen in a particular view is called a(n)______ or_______ line.

A differential equation encountered in the vibration of beams is d4ydx4=2D where x = distance measured along the beam; [x]=[L] y = displacement of the beam; [y]=[L] = circular frequency of vibration; []=[T1] = mass of the beam per unit length; []=[ML1] D = bending rigidity of beam; [D]=[FL2] Show that the equation is dimensionally homogeneous. Note that [F]=[MLT2] see Eq. (1.21:).
