The types of scientific knowledge of force that would enable someone to build a crane could include:
Trusses are triangular units that are used in construction to support the main structure. Put simply, they distribute the forces so that the structure is strong and stable enough to fulfill it's purpose.
It is a scientific machine that applies tension to an item until it fails. It is used for quality control and to know the durability of certain items. It can also determine how certain forces will effect the material. For example, it could predict how certain weather forms effect housing materials.
Different principles apply in the construction of bridges. The main principle is that force is equal to mass times acceleration where all the forces need to balance out. Another principle used is stress, where the materials maximum stress capacity should not be exceeded.
Shear forces are ranged forces pushing one part of a body in a direction and another part in opposite directions. An example is when you pushed a deck of cards one way at the top and another at the bottom causing the cards to slide.
Yes, water beads up on wax paper because its cohesive forces are greater than the adhesive forces.
No, it is not true. There are several areas where our knowledge is deficient. For example, the actual nature of Gravity, or what is the nature of Dark Matter.
Judgments regarding what is normal are based on culture. Culture encompasses the political, scientific, and ethical value systems of a society.
Yes, forces are measured in newtons. I did scientific research on it saying it is.
Forces exist whether there are people, animals, and plants or not. Science just looks at how forces work, and how they relate to movement, acceleration, velocity, work, power, and so forth. So it is not a question of if 'we need scientific forces', at all.

Support, gravity, friction, thrust, centripetal.
That mankind is very vulnerable to beliefs un the unknown and unprovable when there is absence of knowledge of the reality of the physical universe, and myths are used instead to fill the gap. Not much has changed today, even when expanding scientific knowledge has explained natural forces, and it is no longer necessary to invent gods to explain them.
English only
The newton is a unit of force. Examples of forces are gravitational force, electric forces, magnetic forces, forces caused by pressure.
They are small pieces of hardware used in wood construction to connect dimensional lumber where it intersects at 90 degrees. For example, they can be used to connect studs to top or bottom plates. They help to transfer forces from one part of the structure to another, reinforcing against forces such as those produced by wind or earthquakes.
