Question

A broom with an input arm length of .4 meters has a mechanical advantage of .5. What is the length of the input broom

Answer 1

0.2 meters

Explanation:

Mechanical advantage os the amplification of force by a machine. The formulae for calculating mechanical advantage is;

MA = Fᵇ / Fₐ = a/ b

Whereby;

MA = Mechanical Advantage

Fᵇ = Force b

Fₐ = Force a

a = distance a

b = distance b

Therefore mechanical advantage in the question can be calculated as;

MA = a/b

0.5 = a/ 0.4

a = 0.5 * 0.4

a = 0.2

Answer 2

Answer:

0.2 meters

Explanation:

.MA = Fᵇ / Fₐ = a/ b

MA = Mechanical Advantage

Fᵇ = Force b

Fₐ = Force a

a = distance a

b = distance b

It can be calculated as;

MA = a/b

0.5 = a/ 0.4

a = 0.5 * 0.4

a = 0.2
