A block and tackle system has V.R. = 5.(a) Draw a neat, labelled diagram of a system indicating the direction of its load andeffort.

To create a neat and labeled diagram of a block and tackle system with a velocity ratio (V.R.) of 5, we need to illustrate the components and label them accordingly. Here is a written description of what the diagram should include since I'm unable to draw.

Diagram Components

1. Blocks: Draw two blocks, one on top (fixed) and one below (movable).
2. Rope/Cable: A rope runs from the top block to the bottom block and loops back to the top, illustrating the mechanical advantage.
3. Load: On the movable block, represent the load which is being lifted.
4. Effort: Indicate the effort applied at the beginning of the rope (the end that is being pulled down).
5. Directions: Use arrows to indicate:
   • The direction of the load (upward)
   • The direction of the effort (downward)

Here’s how it could be visually structured:

               Load
                |
                ↓
           +---------+
           |  Block  | (Movable block)
           +---------+
                |
               / \
              /   \
             /     \
            +-------+ 
            | Block | (Fixed block)
            +-------+
                |
                ↑
              Effort

Directions

• Load Direction: Upward
• Effort Direction: Downward

This block and tackle system allows the user to lift heavy loads with a smaller effort due to the mechanical advantage created by the arrangement of the blocks and the pulley system.
