Question

Determine the magnitude and direction of the resultant force systems below

 

### Problem 1 #### Task: Determine the magnitude and direction of the resultant force. (10 points) #### Diagram Explanation: The diagram shows three forces acting on a point where a mechanical component is attached to a wooden surface with a bolt: - **40 lb Force**: This force is directed at a 40-degree angle from the positive x-axis. - **30 lb Force**: This force is directed along a line making a 20-degree angle with the positive x-axis. - **20 lb Force**: This force is directed vertically upwards along the y-axis. The forces are applied on the same plane and originate from a common point, indicated by a circular end fixed at the bolt on a wooden surface. The common point is where these forces seem to intersect, and they are vector quantities with specific magnitudes and angles. ### Problem 2 #### Task: Determine the reactions at the supports. (Note: The image's lower section mentions another problem which is not fully visible, so the details about the reactions and conditions are not present.) --- For educators: This problem involves resolving multiple forces, calculating the resultant vector using trigonometric functions, and understanding vector addition principles in physics.
