Missing figures Recoil, commonly referred to as "kick," occurs as a result of Physical properties at work. However, it is often undesirable because it can be uncomfortable for the shooter and can reduce accuracy. The purpose of this webpage is to discuss the physics involved with rifle recoil in order to address various methods of minimizing it. Rifle recoil is most simply explained by Newton's First and Second Laws of Motion. When a rifle is fired, a force is exerted on the bullet that projects it forward. By Newton's 1st Law, it can be inferred that and opposite force will be imposed on the rifle. From Newton's 2nd Law it can be deduced that this force can cause an acceleration (linear or angular) which results in velocity and therefore kinetic energy. Energy is also transferred into the marksman in the form of work. The total of this energy is called Recoil Energy and can be calculated. When a gun is being held at rest, there are three forces acting on it. The weight of the gun pushes downward, and the shooter's hands exert a normal force upward on the gun as shown in Figure 2 below. The point P represents the point of contact between the stalk and the marksman's shoulder. Image - Torque 2 [Figure 2] When the gun is fired, the bullet is projected forward by a force, and an opposite force (F) pushes backward on the gun. Since the barrel where the force is acting is slightly above the point of contact with the shooter's shoulder, torque is created. The normal forces put on the gun by the shooter's hands momentarily become negligible.* The forces acting on the gun directly after the gun is fired can be simplified as in Figure 3. R is the perpendicular distance between the recoil force and the point P. L is the perpendicular distance between the location of the force due to gravity and the point P. The resulting linear and angular acceleration can be seen in Figure 4. Image - Torque [Figure 3] Image - Torque 3 [Figure 4] The elevation caused by the angular acceleration can decrease accuracy by altering the trajectory of the bullet, and the horizontal acceleration causes a force to be exerted on the shooter's shoulder which can be painful. *This suggestion is not completely accurate because the shooter's grip will put a downward force on the gun when the gun is fired.
Ethical issues we face Essay
Ethical issues we face in the day-to-day job or private life Ethics is one of the most important aspects in our daily lives, whether we are employed within an organization or act as members of a society. Issues concerning ethics have increased significantly especially over the last two decades as a result of globalism and of a fast-changing world. Nowadays, the extensive usage of social media requires certain ethical behavior that goes hand-in-hand with the real world. Ethical issues in the workplace.
Ethical issues vary on the type of business an organization is involved in. However, certain issues remain the same and dealing with them is very crucial since their effects on the future of an organization might be devastating. Among them I can mention: Health and Safety
It is important to have a proper balance between the costs of production and the health of employees. All companies must ensure a safe work environment. However, there have been cases where in order to cut spending companies have failed to pay close attention to the health of their employees. Sexual harassment
Sexual harassment is one of most common ethical issues in the workplace behind which a large number of legal trials exist. Asking sexual favors in exchange of promotions is not only unethical but also punishable by law in most of the countries. Conducting personal business on company time
This can significantly impact personal job performance and the overall results of a company. Taking advantage of otherâ€™s work
There are times when we are required to work in a team and thus having an interaction with others when reaching the predetermined goals. Sometimes this can cause that certain individuals might take advantage of otherâ€™s work at a time when their contribution was minimal or lacking professionalism. To tell or not to tell
Observance of improper business practices conducted by managers or fellow employees can cause an ethical dilemma. In such cases we often ask ourselves to tell or not to tell. On one hand we are aware of their wrongdoing andÂ want to report the problem, but on the other hand fear of losing the job cause us to remain silent. Other issues include late arrivals, lying to customers, nepotism, laying off of an experienced workforce and hiring of cheap labor, whistle-blowing etc
Ethical problems in private life
Ethical problems in our private life have a broader range as we are part of more complex environments. Some of them are as follows: Finding money which does not belong to us.
