A stiff rod that rotates around a pivot point is called a lever. It is a type of simple machine that is used to help move a heavy or firmly fixed load.
A wheelbarrow uses a lever as a simple machine to lift a load. The handle of the wheelbarrow acts as the lever, allowing the user to exert a force to lift the load placed in the container.
A fulcrum.
A crane utilizes a combination of simple machines, but the primary one involved in lifting a load is the pulley. The pulley system allows the crane to lift heavy loads with relatively less effort by applying force over a distance.
This simple machine is likely a lever, where the load is on one end and the applied force is on the other. By using a lever, you can lift a load that is double the weight of the force applied due to the mechanical advantage gained.
A block and tackle is a compound machine that combines multiple pulleys to create a mechanical advantage to lift heavy objects. It is commonly used to reduce the amount of force needed to lift an object by distributing the load.
A pulley system uses a wheel with a rod through its center to lift or move a load. The pulley reduces the amount of force needed to lift heavy objects by distributing the weight across multiple ropes or chains.
A pulley is considered a simple machine because it can change the direction of a force and make it easier to lift heavy objects by distributing the load across multiple ropes. It involves a wheel with a groove around its circumference and a rope or chain that fits into the groove, allowing for mechanical advantage. By using a pulley system, one can reduce the amount of force required to lift an object.
A block and tackle is a type of compound machine made of multiple pulleys. It is often used to multiply the force applied to lift heavy objects by using a system of ropes and pulleys to distribute the load.
The bucket of a wheelbarrow is a type of lever, specifically a second-class lever. When you lift the handles, the bucket pivots around the wheel axle as the load is lifted, making it easier to transport heavy objects.

The fulcrum should be placed closer to the heavy load to balance it. By positioning the fulcrum nearer to the heavy load, more leverage can be generated to lift the load with less effort.
Load refers to the force that a machine is designed to move or support. Simple machines, such as levers or pulleys, can either increase the force applied to lift a load or change the direction of the force to make it easier to move the load. Simple machines allow us to accomplish tasks more efficiently by reducing the amount of force or effort needed to move a load.
