To loosen a stuck nut, an inexperience mechanic pulls at an angle of 45⁰ on the end of a 50 cm wrench with a force of 200N. Determine the magnitude of the torque on the nut. If the nut suddenly turns freely, find the angular acceleration of the wrench? ( the wrench has a mass of 3kg, and its shape is that of a thin rod)
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.
