Question
Also find the normal force between the crate and the wedge
**Crate and Wedge** The crate weighs 300 lb and the coefficient of static friction (\(\mu_s\)) at all contacting surfaces is 0.3. Assume the wedges have negligible weight. Find the smallest force \(P\) needed to pull out the wedge. **Diagram Explanation:** The diagram shows a crate resting on a horizontal surface with a wedge inserted underneath it. The wedge is inclined at an angle of \(15^\circ\). The force \(P\) is applied horizontally to the wedge to pull it out from under the crate. Points \(A\) and \(B\) indicate locations on the wedge, possibly related to the points of contact or application of force.
