Answers

Here I hope this is what you need?

When austenite in iron-carbon alloys is transformed isothermally below the eutectoid temperature at small undercooling, it undergoes eutectoid transformation to produce a unique micro- structure termed “pearlite”, which was discovered by Sorby in 1864.

Which forces on the arrow before is released ?

Answers

Hope this helps! :D

There is a very interesting physical phenomenon in the physics behind archery, known as Archer's paradox. When an arrow is released to the left (or right) of a bow its trajectory follows a path that is different from its expected trajectory.

The contradiction, or paradox, arises from the fact that the arrow oscillates during its release, as the string is exerting its "push" force at the rear of the arrow. As a result of this oscillation, the arrow undulates around the bow shaft, enabling it to fly in a trajectory that is in the same direction as the arrow axis at full draw. The video below shows the motion of the arrow just after release, using a high-speed camera. It only takes milliseconds for the arrow to fly past the bow.

What is the last stage of gears?

The last stage of gears found between the vehicle transmission system and the wheels is the final drive ratio. The function of the final drive gear assembly is to enable a gear reduction control stage to reduce the rotation per minute and increase the wheel torque, such that the vehicle performance can be adjusted and the final gear ratio can be between 3:1 and 4.5:1 not 1:1

A gear is a rotating , circular machine element with teeth that can be cut, or in the case of a cogwheel or gearwheel, they can be inserted. These teeth, known as cogs, mesh with another grooved part to transfer (convert) torque and speed.

The basic idea underlying how gears work is comparable to the fundamental idea behind how levers work. Cog is another casual term for a gear. Geared devices can vary the speed, torque, and orientation of a power supply.

Therefore, Technician will say that the differential gear set allows for the difference is speed of each drive wheel when cornering.
