Answer: 24.39 N
Explanation:
Given
Torque required to open the lid is [tex]\tau =2\ N.m[/tex]
diameter of lid [tex]d=8.2\ cm[/tex]
Force exerted by fingers and thumb forms a couple. So, torque can be written as
[tex]\Rightarrow \tau= F\times 2r\\\Rightarrow 2=F\times 8.2\times 10^{-2}\\\\\Rightarrow F=\dfrac{200}{8.2}\\\\\Rightarrow F=24.39\ N[/tex]
Thus, the magnitue of each force is 24.39 N
Answer: T = F x 2pir
2 = F x 8.2 x 10^-2
solve for F:
F = 24.39 N
