Question

Which increases the work output of a machine?

A.increasing friction
B.reducing friction
C.reducing input distance
D.increasing output distance

Answer 1

the answer is B.reducing friction

Answer 2

D. Increasing output distance

Step-by-step explanation:

The work done for any machine is given by:

Output work done of machine = W = Fd

Where,

F = output force

d = output distance

Output work of machine can only be increased by increasing output force or output distance. Hence, in the current situation output work of machine can be increased by increasing output distance.
