If M = 0.50 kg, L = 1.2 m, and the mass of each connecting rod shown is negligible, what is the rotational kinetic energy about an axis perpendicular to the paper through the center of mass after 5- revolutions in 5-min, starting from rest? Treat the masses as particles.
Angular speed, acceleration and displacement
Angular acceleration is defined as the rate of change in angular velocity with respect to time. It has both magnitude and direction. So, it is a vector quantity.
Angular Position
Before diving into angular position, one should understand the basics of position and its importance along with usage in day-to-day life. When one talks of position, it’s always relative with respect to some other object. For example, position of earth with respect to sun, position of school with respect to house, etc. Angular position is the rotational analogue of linear position.
If M = 0.50 kg, L = 1.2 m, and the mass of each connecting rod
shown is negligible, what is the rotational kinetic energy about an
axis perpendicular to the paper through the center of mass after 5-
revolutions in 5-min, starting from rest? Treat the masses as
particles.
