Create a clear landscape 4:3 educational bitmap comparing an ideal fixed pulley and an ideal movable pulley for introductory physics. Divide a warm-white canvas into two equally sized panels. Left: one pulley fixed to a rigid overhead support, a continuous rope over its wheel, a suspended load at one end and a downward pull arrow at the other. Right: one rope end fixed to the overhead support, the rope passing under a pulley attached to the same-size load, and the free end pulled upward; visibly show two supporting rope segments. Use exact short labels only: 'Fixed', 'Movable', 'Load', 'Pull', and add 'Ideal model' once. Do not show numerical force values. Color ropes ochre, supports slate and force arrows teal; realistic simple cutaway wheels with flat explanatory arrows. Keep routing mechanically correct, labels readable and generous whitespace. No floating load connections, crossed ropes, decorative gears, extra mechanisms or watermark.
