TAPER TURNING - Practice Mode
1) Which instrument can measure angle upto an accuracy of 5 minutes?
2) Which part is pivoted to the disc of vernier bevel protractor?
Explanation:
Plasticity:
Plasticity is the property by which a metal retains its deformation permanently, when the external force applied on it is removed.
Examples: forming, forging, hammering
Brittleness
Brittleness is a property of material which breaks with little or no deformation.
Elasticity:
Whenever an external force is applied on a metal, it deforms. Elasticity is the property by virtue of which a metal regains its original shape when the external force applied on it is removed.
Ductility:
Ductility is the property by which a metal can be drawn into thin wires. It is determined by percentage elongation and percentage reduction in area of a metal.
3) Which is the smallest unit of angular measurement?
Explanation:
Elasticity:
Whenever an external force is applied on a metal, it deforms. Elasticity is the property by virtue of which a metal regains its original shape when the external force applied on it is removed.
es: forming, forging, hammering

Malleability:
Malleability is the property by which a metal can be rolled into thin sheets. Highly malleable metals (like Mild Steel) are extensively used in making sheet metals.
