Load is between force Wheelbarrow 2nd Class Nutcracker and fulcrum. Lever Effort, Load, FULCRUM Force is between Bent Arm 3rd Class Fishing Rod resistance and fulcrum. Lever Load, Effort, FULCRUM Wheel with a rod (axle) Cars Roller Skates through its center. Used Wheel & Door Knobs to lift or move loads. Gears Axle An axle is a rod that goes through the wheel and allows the wheel to turn. Cord wraps around a Flag Poles Sailboat wheel. Used to move Blinds objects (esp. heavy) to Crane hard-to-reach places, up down, or sideways. As the wheel rotates, the cord moves in either direction. Works with gravity to be easier for user. Pulleys Saves effort when you have more than one pulley working together. Increase the number of pulleys, increase the distance that the rope must be pulled. Types of Pulleys: Fixed Movable Single Combination
