PhysCasts: A Suspended Nonuniform Bar
Hall, B. (Brenton) (2013)
The following PhysCast deals with a non-uniform bar which is suspended and in static equilibrium. A nonuniform bar is suspended at rest in a horizontal position by two massless cords. One cord makes the angle theta = 36.9 degrees with the vertical; the other makes the angle phi = 53.1 degrees with the vertical. If the length of the bar is 6.10 m, compute the distance x from the left end of the bar to its centre of mass.
