Final answer:
The effort distance to balance the load in the wheelbarrow is 1.02 meters.
Step-by-step explanation:
In order to calculate the effort distance to balance the load in a wheelbarrow, we can use the concept of mechanical advantage. The mechanical advantage of a lever is given by the ratio of the length of the effort arm to the length of the resistance arm.
In this case, the effort distance is the length of the hands' perpendicular lever arm, which is 1.02 m. Therefore, the effort distance to balance the load in the wheelbarrow is 1.02 meters.
The complete question is: A student uses an effort force on a lever to balance a load of mass 5 kg. The load arm is 84 cm and the effort arm is 24 cm. Convert centimeters to meters.
