Homework Help Overview

The problem involves determining the forces exerted on a resting ball by two wooden boards, given a weight of 100 N for the ball and the assumption of no friction. The context is centered around static equilibrium and force analysis.

Discussion Character

  • Exploratory, Problem interpretation, Assumption checking

Approaches and Questions Raised

  • Participants discuss the calculation of forces using trigonometric functions, specifically referencing the cosine of angles in relation to the weight of the ball. There is mention of drawing a free body diagram and writing equilibrium equations.

Discussion Status

Some participants have attempted calculations and shared their results, but there is uncertainty regarding the correctness of these calculations. The discussion is ongoing, with participants exploring different interpretations of the problem setup.

Contextual Notes

There is a reference to the need for a free body diagram and equilibrium equations, suggesting that the problem may involve multiple forces acting on the ball that need to be considered together.

Have a go yourself first.
 
I got 70.71 N by doing 100cos(45). I have no idea whether or not this is correct.

There are two boards exerting contact forces on the ball. Call these each F. Draw a free body diagram, and write down the equations in order for the ball to be in equilibrium.
