Is the block of wood floating in water? If so, then a drop of dishwashing soap dropped into the water next to the wood, will cause the wood to float away from the drop of soap. The effect is quite pronounced on small pieces of wood, and it is positively dramatic on tiny things like parsley flakes floating on the water.
What's happening is that the piece of wood floating in the water is acted on by the surface tension of the water. The water pulls in every direction, so the wood doesn't move. A tiny drop of soap will break the surface tension of the water, and the surface tension on all the OTHER areas of water will cause the wood to be pulled away from the soap drop.

What is shear force?
Shear force is an internal force in any material which is usually caused by any external force acting perpendicular to the material, or a force which has a component acting tangent to the material. Take a ruler or a block of wood, and put it in table surface. Pushing the ruler or the block of wood in the downwards direction, will create a shear force inside the block of wood or the ruler. Since you are creating a force that's perpendicular to the material. The bigger force you apply to the ruler or the block of wood, the higher the shear force the material is going to experience in general. Please note shear force is an internal force, and in the block of wood or the ruler in this case, the shear force can vary at different point in the material. You can also draw a shear force diagram which represent how much shear force a material is experiencing at different point.
Why is a nail pointed at the end?
The point is a "wedge" that separates the wood fibers as the nail enters, making it easier to drive into the wood without tearing the wood as a flat tipped nail would.
Is plywood fire proof?

What is the difference between wood lathe machine and wood lathe duplicator?
A lathe has one workpiece spinning on an axis, which the operator holds a tool to to cut the material. A duplicator has two workpieces, and a probe touching one piece causes a tool to cut in to the other, creating a duplicate of the probed piece.
Why plywood is so strong?
Simply because the wood grain in each layer of the plywood - is laid at 90 degrees to the one it's touching. If the grain was laid the same way throughout - the wood would have a weakness along the length of the grain.

Why you can easily move your hand in air but to do the same through a solid block of wood you need a karate expert?
the air has a lot of intermolecular space between them so yuo can easily move your hand through it. But the block of wood has the particles tightly packed and hence you need a karate expert to break the block of solid wood.
What is the hypothesis when a block of wood is moved over a worktop?
When a block of wood is moved over a worktop, my hypothesis would be, someone has moved it. Wood blocks are seldom known to move on their own. Alternatively, it could have been an earthquake.

The weight of water displaced by the floating block of wood is exactly equal to the weight of the ENTIRE block of wood, regardless of how much of the wood is above the water level.
What change could be made in the setup in diagram 1 to increase the amount of force necessary to move the block of wood?
yes
