The blade of a metal cutter are shorter than that of blades of paper cutter scissors ? give reason i will give brainliest​

This is because, metal cutters need more pressure in order to cut the metal. The more shorter the blade, the more pressure and force is has in order to help cut the metal. Scissors have longer blades because they don’t require as much force and pressure since they cut easier materials than metal.

the simple machine has three main features. they are:

loadfulcrumeffort

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are
