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.

Explain, using at least three reasons, why Timothy would fail to be a good match as a mechanical engineer in the following scenario. Situation: Timothy is a very shy, reserved person. He is very artistic and creative, but math and science were never his strong subjects. As he enrolls in college classes, he is looking to be exposed to many different careers. He would like to go to an office every day, complete his work, and leave with a sense of accomplishment. He does not enjoy long-standing projects and assignments.

Answers

Answer:

Based on the scenario provided, Timothy is unlikely to be a good match as a mechanical engineer for the following reasons:

Lack of Strength in Math and Science: Mechanical engineering requires a strong foundation in math and science, as these are the fundamental principles that underpin the field. Timothy's lack of strength in these subjects suggests that he may struggle to understand the complex calculations and scientific principles required to be a successful mechanical engineer.

Preference for Short-term Projects: Mechanical engineering involves working on long-standing projects, which require sustained effort and attention to detail. Timothy's preference for short-term projects and assignments suggests that he may struggle to remain motivated and focused over long periods of time, which could result in subpar performance and unsatisfactory results.

Incompatibility with the Work Environment: Timothy's desire to work in an office every day, complete his work, and leave with a sense of accomplishment is not well-suited to the fast-paced, dynamic work environment of mechanical engineering. Mechanical engineers often work in industrial or manufacturing settings, where they must work on multiple projects simultaneously and be prepared to deal with unexpected challenges and obstacles.

In summary, Timothy's lack of strength in math and science, preference for short-term projects, and incompatibility with the work environment make him an unlikely candidate for success as a mechanical engineer.

What is the name of the two-phase microstructure found in steels resulting from the eutectoid transformation of austenite and consisting in alternate layers of ferrite and cementite

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.
