Question

Write four uses of wedge.
in point wise ​

Answer 1

Answer:

Wedges are used to lift heavy objects, separating them from the surface upon which they rest.[3]

Consider a block that is to be lifted by a wedge. As the wedge slides under the block, the block slides up the sloped side of a wedge. This lifts the weight FB of the block. The horizontal force FA needed to lift the block is obtained by considering the velocity of the wedge vA and the velocity of the block vB. If we assume the wedge does not dissipate or store energy, then the power into the wedge equals the power out.

or

The velocity of the block is related to the velocity of the wedge by the slope of the side of the wedge. If the angle of the wedge is α then

{\displaystyle v_{\mathrm {B} }=v_{\mathrm {A} }\tan \alpha ,\!}{\displaystyle v_{\mathrm {B} }=v_{\mathrm {A} }\tan \alpha ,\!}

which means that the mechanical advantage
