Transcribed Image Text:**Text:**
A laborer needs to hold a 200 lbs weight above a truck bed. With the given geometry shown in the diagram below, what force (F) does this person need to pull with? Assume the mast exerts a force (as a vector) along its axis. Hint: The force (F) does not necessarily equal 200 lbs.
**Diagram Explanation:**
The diagram illustrates a person standing on a flat surface, pulling a rope attached to the top of a mast. The force exerted by the person is labeled as "F" and extends at an angle of 20° from the horizontal. The mast, extending from the bottom to the top, is inclined at an angle of 30° from the horizontal, holding the 200 lbs weight at its top. The angles suggest a mechanical advantage and require calculating the actual force needed based on vector components.
