Each time the body demonstrate difficult and critical angle because of the spring like elasticity (plate 25A-E). The elasticity of the body muscles and the joints performs some of the most amazing acute angles with grace and balance (plate 25B). We need to understand that human body appears to work like spring. It can contract (plate 25A), store energy (plate 25C) while spinning and expand like a spring (plate 25D). At the same time it maintains its equilibrium (plate 25C) with the help of difficult balancing factors. Depending upon the material it may stretch and come back in place like a rubber band.
