Efficiency=(AMAIMA)×100%Efficiency equals open paren the fraction with numerator AMA and denominator IMA end-fraction close paren cross 100 %

(1) 80 N, (2) 12, (3) 70%, (4) False – Friction always exists.

A lever system has an effort arm of 2 meters and a load arm of 0.5 meters. If 50 N of input force is applied, what is the ideal mechanical advantage and the maximum output force possible (assuming no friction)? Because friction always resists motion in the real

Because friction always resists motion in the real world, the AMA of a machine is always less than its IMA . 2. What is Efficiency?

Leo looked up at the heavy chain. "And if they tried to lift double... and the efficiency was actually 50%..." Leo looked up at the heavy chain

= (Work output / Work input) × 100%
