B. Normal platelets
C. Too many platelets
D. Does not effect
A. Steel
B. Rubber
C. Glass
D. Sponge
E. None of these
STEEL is most elastic among the rubber, steel, glass and sponge. Steel having the most steep linear stress-strain curve among all.
A stiffer material will have a higher elastic modulus.
Young’s Modulus alt. Modulus of Elasticity – is a measure of stiffness of an elastic material.
Young’s modulus for steel- 200 GPa
Young’smodulus for glass – 50–90 GPa
Young’s modulus for rubber – 1 MPa
Young’s modulus for sponge – 2–4 GPa
A material with a higher Young’s modulus is more elastic.
Lack of _______ causes diabetes?
A. Vitamins
B. Sugar
C. Insulin
D. Calcium
