5. if a machine has an ima of 8 and an ama of 6, what is the machines efficiency? hint: efficiency is the comparison of what you get out of a machine (ama) compared to what you ideally should get (ima).

5. if a machine has an ima of 8 and an ama of 6, what is the machines efficiency? hint: efficiency is the comparison of what you get out of a machine (ama) compared to what you ideally should get (ima).

Answer

Explanation:

Step1: Definir la fórmula de eficiencia

La eficiencia ($\eta$) de una máquina se define como $\eta=\frac{AMA}{IMA}\times100%$, donde $AMA$ es la fuerza mecánica aparente y $IMA$ es la fuerza mecánica ideal.

Step2: Sustituir valores

Dado que $IMA = 8$ y $AMA=6$, sustituimos en la fórmula: $\eta=\frac{6}{8}\times100%$.

Step3: Calcular el resultado

$\frac{6}{8}\times100% = 0.75\times100%=75%$.

Answer:

$75%$
