AI Thread Summary
The discussion focuses on solving a physics problem related to the forces acting on a bowler's arm. Participants suggest starting with a free body diagram of the lower arm to identify all forces and reactions. There is uncertainty about the correctness of the free body diagram and the calculation of force F4. The method for balancing forces and moments is questioned, particularly for parts a and b of the problem. Clarification on these points is sought to ensure the approach is accurate.

The Attempt at a Solution



I'm not sure at all how to solve this problem. If anyone can help me out with setting this up and proceeding from there that would be a big help.

start with a free body diagram of the lower arm showing all forces and reactions, then balance forces and moments

Is that free body diagram correct and what would the force be on F4? And is my method for part a and b correct?
 
Anyone know if the above is right?

Thread 'Minimum mass of a block'

Here we know that if block B is going to move up or just be at the verge of moving up ##Mg \sin \theta ## will act downwards and maximum static friction will act downwards ## \mu Mg \cos \theta ## Now what im confused by is how will we know " how quickly" block B reaches its maximum static friction value without any numbers, the suggested solution says that when block A is at its maximum extension, then block B will start to move up but with a certain set of values couldn't block A reach...

Thread 'Electric field due to charges between 2 parallel infinite planes'

TL;DR Summary: Find Electric field due to charges between 2 parallel infinite planes using Gauss law at any point Here's the diagram. We have a uniform p (rho) density of charges between 2 infinite planes in the cartesian coordinates system. I used a cube of thickness a that spans from z=-a/2 to z=a/2 as a Gaussian surface, each side of the cube has area A. I know that the field depends only on z since there is translational invariance in x and y directions because the planes are...

Thread 'Calculation of Tensile Forces in Piston-Type Water-Lifting Devices at Elevated Locations'

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...
