Answer:
Option C
Explanation:
From the question we are told that:
[tex]IMA=7[/tex]
Effort force [tex]F_e=5N[/tex]
Effort distance [tex]d_e=4m[/tex]
Generally the equation for IMA is mathematically given by
In Terms of Distance
[tex]IMA=\frac{d_e}{d_x}[/tex]
[tex]7=\frac{4}{d_x}[/tex]
[tex]d_x=0.57m[/tex]
In Terms of Force
[tex]IMA=\frac{F_x}{F_e}[/tex]
[tex]7=\frac{F_x}{5}[/tex]
[tex]F_x=35N[/tex]
Therefore
[tex]F_x=35N[/tex] and [tex]d_x=0.57m[/tex]
Option C
