Question
b.6
![**Problem Statement:**
The force \( P \) is applied to (a) the 71-lb block and (b) the 126-lb block. For each case, determine the magnitude of \( P \) required to initiate motion.
**Diagram Description:**
The diagram depicts two blocks on a surface with arrows indicating the direction of applied forces. The blocks have the following attributes:
1. The top block (Block A) weighs 71 lb with a coefficient of static friction (\( \mu_s \)) of 0.35.
2. The bottom block (Block B) weighs 126 lb with a coefficient of static friction (\( \mu_s \)) of 0.18.
There are two indicated forces:
- \( P(a) \) applied to the 71-lb block.
- \( P(b) \) applied to the 126-lb block.
The goal is to calculate the magnitude of \( P \) for each scenario to initiate motion.
**Answers:**
(a) \( P = \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ lb \)
(b) \( P = \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ lb \)](https://content.bartleby.com/qna-images/question/c59a6d07-a993-40f7-b57e-cdb2ad079d78/10c8bca2-386b-4c4b-b790-9a5df9f29903/hfmmq6h_thumbnail.png)
