The Progressive Group Task (PGT), Half Group Task and the Command Task are based on the
principles of cantilever. A cantilever beam is one which is fixed at one end and free at the other end
and is supported by a fulcrum. Figure 1 shows a cantilever arrangement. It may be seen that the plank

is resting on the goalpost kind of structure (fulcrum) and one end of the plank is fixed by inserting it
inside the ‘A’ like structure. Get this principle firm in your mind. Whenever you are approaching the
obstacles, look for how you can make a cantilever. In most cases, the only way to move from one
structure to the other is by walking on either the plank or the balli. The challenge is to fix one of them
in such a way that it supports the weight of the person. Therefore, first thing is to take the plank in
your hand as it is more stable than the balli and look for a place (fulcrum) where it can be
rested/supported. Having Kept the plank/balli on the fulcrum, look for arrangements which can be
used to fix one end. Pictures 2 to 6 depict various simple cantilever arrangements that can be made

using the helping material and structures that are normally given at the SSBs.
