Hey mate here is your answer ⬇️⬇️⬇️⬇️

WHEN ONE INCREASES THE OTHER MUST DECREASE. THIS IS BECAUSE THE WORK OUTPUT IS NEVER GREATER THAN THE WORK INPUT. ... MECHANICAL EFFICIENCY=WORK OUTPUT/WORK INPUT X 100 Page 2 NO MACHINE IS 100 PERCENT EFFICEINT, BUT REDUCING THE AMOUNT OF FRICTION IN A MACHINE IS A WAY TO INCREASE ITS MECHANICAL EFFICIENCY.
