Question

Effort arm of a lever is 80 cm. Mechanical advantage is 1 . Calculate the length of a lever .

Answer 1

Answer:

0.16m

Explanation:

Length of effort arm = 0.8m

Mechanical advantage = 1

let the length of load arm be x

$</p><p>mechanical \: advantage = \frac{length \: of \: effort \: arm}{length \: of \: load \: arm}$

$1 = \frac{0.8}{x}$

the length of load arm = 0.8m

the length of lever = length of effort arm + length of load arm

= 0.8 + 0.8

= 0.16m or 160cm
