प्रश्न
What is a wedge? Give two examples.
उत्तर
A wedge is a double inclined plane such that the two sloping surfaces taper to form either a sharp edge or a pointed edge.
Examples: A knife, an ax, a chisel.
In some special cases, the number of inclined planes used can be more than two as well. In such cases, the sloping surfaces generally taper to form either a very sharp or a pointed edge to split or pierce materials. Pins, nails, and needles are examples of pointed wedges. The front end of a boat is shaped like a wedge so that it can easily cut across the flowing water.
The wedge works on a principle of an inclined plane.
