the rectangular plate is shown in figure is held in equilibrium by the horiznatal force F. the weight acts at the midpoint of the plate. determine the angle a at which the plate is in equilibrium for different ratios of F/W. the range of variation of the ratio b/h and F/W are as shown below.
F/W = 0 to 5
b/h = 1 to 10

Answer:
The distance of Centre Of Mass of given right angled triangle is
3
2L
along BA and
3
L
along AC from the point B.
Force of magnitude mg is acting downwards at its COM.
Moment balance around B gives:
mg(
