1.	The strain stress curves of three wires of different materials are shown in the figure. P, Q and R are the elastic limits of the wires. The figure shown thatA. elasticity of wire P is maximumB. elasticity of wire Q is maximumC. tensile strength of wire R is maximumD. None of the above
Answer» Correct Answer - c As stress is shown `Y = cot theta = (1)/(tan theta) = (1)/("slope")` So, elasticity of wire P is minimum and or wire R is maximum.
