Draw a typical Stress-Strain curve for a metal . Mention yield point and fracture point.

Draw Stress - Strain curve. Show Yield point and Fracture point.

Write stress-strain curve for a metal. What is proportional limit and yield point ?

What is an equipotential surface? Draw the equipotential surfaces for i) a uniform electric field and ii) a point charge.

What is toroid? Mention an expression for magnetic field at point inside a toroid.

The curve y-e^(xy)+x=0 has a vertical tangent at the point :

Write one example of each of the following : (i) Most malleable metal and most ductile metals. The best condcutor of heat and the poorest conductor of heat. (iii) A metal with highest melting point and a metal with lowest melting point.

Metals having low melting point are refined by….

Give Reason. Most of the transition metals have high melting point and boiling point.
