Question

Hang gliding is an air sport or recreational activity in which a pilot flies a light, non-
motorised, foot-launched, heavier-than-air aircraft called a hang glider. Most modern hang

gliders are made of an aluminium alloy or composite frame covered with synthetic sailcloth to
form a wing. Typically the pilot is in a harness suspended from the airframe, and controls the
aircraft by shifting body weight in opposition to a control frame.
Aakash, an aeronautical engineer, prepared a model Hang glider using coordinate
system.
