Question
2. Block B has a mass, mb, and is supported as shown. What is the maximum value of mb that can be lifted under force P = 300 lb applied to block A as shown? The static coefficient of friction on all surfaces is 0.2.
### Diagram Explanation The image depicts a scenario involving two blocks, labeled A and B, with respective angles and forces. Here's a detailed breakdown: - **Block A**: - Positioned on a horizontal surface, represented as a blue rectangle. - The angle between the horizontal surface and the upward diagonal line is labeled as \(30^\circ\). - **Block B**: - Depicted as a blue triangle extending from the top of Block A. - Situated to the right of Block A, with its base angled against a wall. - **Forces and Angles**: - A force labeled \( P \) is applied horizontally to the left of Block A. - The right wall is shown with diagonal black stripes, and the angle between this wall and the block is marked as \(60^\circ\). This setup could be used to explore concepts of static and dynamic equilibrium, friction, and the resolution of forces in physics and engineering contexts. The angles suggest examining scenarios involving inclined planes and the effects of forces applied at various angles.
