Yes, the position of the fulcrum affects the force required to lift a weight. Placing the fulcrum closer to the load reduces the effort needed to lift the weight. Conversely, placing the fulcrum further from the load increases the force needed to lift the weight.
If you have two objects of equal weight on either end of a lever, then they must be equidistant from the fulcrum to make the lever balance.If one object weighs more than the other, then that one has to be closer to the fulcrum.
The wheel and axle on a wheelbarrow serve as the fulcrum, allowing for balanced movement and proper distribution of weight when lifting or moving objects.
The part of the lever that bears the weight to be lifted is called the fulcrum. It acts as the pivot point around which the lever rotates to lift the load.
Yes, the force applied is calculated by multiplying the force by the distance from the fulcrum. In this case, the torque applied would be 18 Nm (9 N * 2 m). Whether it is enough to lift the weight depends on the weight and the distance from the fulcrum at which it is placed.
Assuming the fulcrum is at the center, the weight would be lifted if the clockwise torque (force x distance) applied by the 9-N force is greater than the counterclockwise torque of the weight. If the weight is closer to the fulcrum, it may not be lifted, even with a 9-N force.

Consider a wheelbarrow: When the weight is closer to the wheel, there is less load on the lever or handle. M = F*d Moment = Force x distance In this case, force is the mass of the object in the wheel barrow, and distance is distance from fulcrum. So, the smaller the distance, the lower the "moment" or lifting effort. When the distance = the length of the lever, you are basically lifting the entire force.
say its left of the fulcrum, then its (9*2)18 n-m anti clockwise torque, to balance this ,to the right of the fulcrum, force * distance needs to be 18, any combination will do, 2*9,3*6,6*3 etc , this is clockwise torque (

The fulcrum should be moved closer to the child in order for the child to lift the adult. Placing the fulcrum closer to the lighter weight (child) increases the mechanical advantage, allowing the child to exert a greater force and lift the heavier weight (adult).
The weight needed to balance the lever depends on the distance of the weight from the fulcrum and the weight on the other side of the lever.
