Combined Motion of Rotation and Translation
INTRODUCTION We have already discussed in chapter 17 linear motion or motion of translation. And we have also discussed in the last chapter motion of rotation. But sometimes a body…
Motion of Rotation
INTRODUCTION Some bodies like pulley, shafts, flywheels etc., have motion of rotation (i.e., angular motion) which takes place about the geometric axis of the body. The angular velocity of a…
Projectiles
INTRODUCTION In the previous chapters, we have been discussing the motion of bodies, either in horizontal or vertical directions. But we see that whenever a particle is projected upwards at…
Relative Velocity
INTRODUCTION It has been established since long that every motion is relative, as an absolute motion is impossible to conceive. Strictly speaking, our motion is always relative with reference to…
Motion Under Variable Acceleration
INTRODUCTION In the last chapter, we have discussed the motion under constant acceleration, i.e., the rate of change of velocity was constant. But in actual practice, it is seldom possible, that…
Linear Motion
INTRODUCTION A body is said to be at rest, if it occupies the same position with respect to its surroundings at all moments. But it is said to be in…
Virtual Work
INTRODUCTION It has been observed that whenever a force acts on a body, and the body undergoes some displacement, some work is said to be done. Mathematically, if a force…
Equilibrium of Strings
INTRODUCTION A string (or rope), in its theoretical sense, is absolutely flexible, light (i.e. its weight is neglected) and inextensible. It is capable of offering only tensile resistance. The slope of…
Analysis of Perfect Frames (Graphical Method)
INTRODUCTION In the previous chapter, we have discussed the analytical methods for determining the forces in perfect frames. We have seen that the method of joints involves a long process,…
