The image consists of two diagrams labeled (a) and (b), illustrating a person using a pulley system. **Diagram (a):** - A person is holding a horizontal bar labeled between points A and B. - The bar is connected by ropes to a pulley system. - The ropes run vertically and are attached to the ceiling and the floor. - The person stands on a surface labeled C. - This setup shows the basic mechanical arrangement for a pulley exercise. **Diagram (b):** - Similar to diagram (a), this arrangement also features a person holding a horizontal bar labeled between points A and B. - The bar is connected to ropes, passing through pulleys at the ceiling. - Like figure (a), the person stands on a surface labeled C. - This setup also demonstrates a pulley system, emphasizing different mechanical principles or configurations. Both diagrams illustrate the concept and use of pulley systems in exercise or mechanical advantage setups.
