Question

The answers are t F2= 2725N, F3= 2180N (left), F4= 2616N(up) but dont know to get there. 

 

**Diagram Description** In the provided diagram, we have a structure labeled "EXIT 40," with various forces acting on it. 1. **Forces**: - \( F_1 = 981 \, \text{N} \) acting downward from the "EXIT 40" structure. - \( F_2 \) is shown acting along a curved path, with its effect seemingly in the general downward and right direction. - \( F_3 \) is depicted as a horizontal force pointing to the right. - \( F_4 \) is a vertical force pointing downward. 2. **Dimensions**: - A vertical distance of 6 meters is indicated down from the "EXIT 40" structure. - A horizontal length of 8 meters extends from beneath "EXIT 40" to a point directly below the point where \( F_2 \) emerges. - An additional horizontal length of 2 meters follows from this point to the locus of \( F_3 \). 3. **Objective**: - The task involves determining the magnitude, direction, and sense (direction) of the forces \( F_2 \), \( F_3 \), and \( F_4 \). This educational scenario likely involves principles of static equilibrium, requiring application of concepts such as vector resolution, moments, and force balance equations to solve for unknowns.
