answer the question No-d

 Initial modulus or stiffness: Fiber stiffness is commonly determined by the initial slope of the stress-strain curve at the origin. This is commonly known as the initial modulus; the higher initial modulus, the stiffer the fiber and the lower initial modulus, the more flexible the fiber.
