Concept explainers

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.

*9. CD mmh A rod is lying on the top of a table. One end of the rod is hinged to the table so that the rod can rotate freely on the tabletop. Two forces, both parallel to the tabletop, act on the rod at the same place. One force is directed perpendicular to the rod and has a magnitude of 38.0 N. The second force has a magnitude of 55.0 N and is directed at an angle 0 with respect to the rod. If the sum of the torques due to the two forces is zero, what must be the angle 0?
Two buckets of mass ?1=19.7 kgm1=19.7 kg and ?2=11.9 kgm2=11.9 kg are attached to the ends of a massless rope which passes over a pulley with a mass of ?p=7.13 kgmp=7.13 kg and a radius of ?p=0.250 m.rp=0.250 m. Assume that the rope does not slip on the pulley, and that the pulley rotates without friction. The buckets are released from rest and begin to move. If the larger bucket is a distance ?0=1.55 md0=1.55 m above the ground when it is released, with what speed ?v will it hit the ground?
