How does reducing friction affect the mechanical advantage and efficiency of a machine?
You can use this on a class website, blog, study group forum, or LMS (like Google Classroom, Canvas, Schoology). How does reducing friction affect the mechanical advantage
a) ( IMA = \fracd_\textind_\textout = \frac15 , \textm1.5 , \textm = \mathbf10 ) b) ( \textEfficiency = \fracAMAIMA \times 100% = \frac810 \times 100% = \mathbf80% ) While this is a reliable guide, it's always
$W_out = 25\text N \times 2.0\text m = 50\text J$ Section 14
: The following answers are based on a commonly used worksheet for this section. While this is a reliable guide, it's always best to use your own textbook or course materials as the final reference.
IMA=dinputdoutput=6.0 m1.5 m=4.0IMA equals the fraction with numerator d sub input end-sub and denominator d sub output end-sub end-fraction equals the fraction with numerator 6.0 m and denominator 1.5 m end-fraction equals 4.0 Step 3: Calculate AMA.
Efficiency is usually expressed as a percentage, such as 3. Section 14.3 Key Terms & Definitions Resistance Force ( Frcap F sub r
