Henry can use a simple machine, such as a ramp or lever, to help him lift the apple baskets into the truck. By using a ramp, Henry can reduce the force needed to lift the basket by increasing the distance over which he applies the force. Alternatively, he could use a lever to amplify his force and lift the basket with less effort. By positioning the fulcrum of the lever in the right spot, Henry can apply a smaller force to lift the basket. This way, Henry can use his limited strength and still get the job done efficiently.
