Question

what are two ways that machines make work easier?

Answer 1

Reducing friction is one

Answer 2

reducing friction
reducing components
obviously advancement in design
reducing strain
avoiding overload
proper maintenance
and a lot more

Answer 3

reduced force is needed to use a machine, but a greater distance must be moved. Machines don't actually make work any less, they make the applied force less, so we think we're doing less work.
