Mechanical Engineering QUESTION #2455

Question 20

For a square-threaded power screw with pitch diameter $d_m$, lead $l$, and coefficient of friction $\mu$, the condition for self-locking is:

$\mu < \tan\lambda$
$\mu = \tan\lambda$
$\mu \geq \tan\lambda$ where $\lambda$ is the thread lead angle✔️
$\mu > \frac{l}{\pi d_m^2}$

Correct Answer Logic:

The self-locking condition: $\pi\mu d_m \geq l$. Since $\tan\lambda = l/(\pi d_m)$, this reduces to $\mu \geq \tan\lambda$. When this condition holds, the load cannot back-drive the screw.
