### Angular Velocity

What is Angular Velocity? Give Definition and Formula?

It is the rate of change of angular displacement of a body. It is usually expressed in revolutions per minute (r.p.m.) or radians per second (rad/s). It is denoted by a Greek letter Ï‰ (Omega). Since it has magnitude and direction, therefore it is a Vector quantity.

If a body is rotating at N r.p.m, then corresponding angular velocity,

Note: If the body is rotating at Ï‰ rad/s along a circular path of radius r, then its linear velocity (v) is given by:

v = Ï‰.r

### Are Engineers Favourite Among Girls?

What do girls think about men who are engineers and what type of engineers are most favourite among girls? A survey was conducted by a team of aboutmech with members chosen from different countries. Each team member carried out a neutral survey in his/ her country to evaluate what females think about most of the engineers from different engineering branches. An overview of different questions asked in survey is given below: Question: Which male engineers do you find more attractive as a husband? Almost 50% women voted for mechanical engineers to be the most attractive husbands among other engineers. So mechanical engineers are most favourite among girls as a husband. They find them more trustworthy, intelligent, and creative. A married women from California said, “If your husband is a mechanical engineer, he will help you in everyday tasks. Because mechanical engineers are good team players and they have creative ideas about everything.” Which male engineers do you find more
