Wood is often used to store things on or lift with as it is strong enough, yet has a bit of flexibility. The surface of the wood is quite forgiving, in the sense that it is less likely to damage heavy goods, unlike metal on metal.
^^^^^ This above doesnt explain the physics really behind it.
We use a length of wood to lift heavy loads due to the leverage it creates. This comes from the principle of moments. When there is a greatr distance from the pivot, this means that there will be less force needed to lift the heavy load upon the plank of wood at the fulcrum. The same applies for why we use a wrench to screw something and not our fingers. This increases the distance from the pivot, and thus we can exert less force upon the pivot to turn the screw. Hopefully this analogy worked for you.

Is a block and tackle an example of a rotational force transformer?
is a system of two or more pulleys with a rope or cable threaded between them, usually used to lift or pull heavy loads.
Why use a winch to lift loads?
A winch puts the force into itself and so its easier for you to lift it
A sentence with fulcrum in it?
move the plank closer to the fulcrum to be able to lift the rock off the ground
How do you you lift a heavy object without a forklift?
That depends how high you want to lift it.
What is the function of a pulley?
1. To change the direction of a cable control. 2. Multiple pulleys will decrease the force required to lift or pull a weight. 3. Used to control tension and slack in a belt drive. People use Archimedes' invention of the pulley to pull and lift heavy things easily. Pulleys are made of ropes, handles, and usually metal.
How does lift effect on a F-15 eagle jet?

How do you lift a heavy box with a lever?
A heavy box can be lifted by the simple machine of a lever. Using a plank as the and rod (or similar) as the fulcrum, the box can be lifted, tilted and possibly flipped by applying force to one side of it.
What is a sloping surface used to move heavy loads up or down?
A sloped surface is used to help lift a load up.
Was there more male slave or more female slaves?
Probably male, because they could do more hard labor. They could lift heavy weights and pull heavy loads.
Can screw jack used to lift smaller loads?
Can be used to lift moderately heavy objects. You need to be familiar with with its lifting capabilities. Make sure that the connections above and below the Jack are secure
What is a block and takle?
A block and tackle is a system of two or more pulleys with a rope or cable threaded between them, usually used to lift or pull heavy loads
How cranes lift heavy loads without toppling?
Because anticlockwise torque is equal to clockwise torque and therefore the net torque is zero so the crane is in state of equillibrium and also there center of gravity pass through base therefore the cranes lift heavy load without toppling
How do you manually you safely lift and carry loads?
NO
How do you pick up carry heavy loads from the floor?
Never bend from the waist. Instead, bend your knees and stoop; lift with your thighs and legs, keeping the load close to your body.
