Kelvin Plank Statement:
Sol: It is impossible to construct this type of H.E. that operates on cyclic process and converts all the heat supplied to it into equivalent amount of work. The conclusions stated below can be made from statement
1. No cyclic engine can converts whole heat into equivalent work.
2. There is degradation of energy in a cyclic heat engine as some of the heat has to be degraded or rejected.
Therefore second law of thermodynamics is called as law of degradation of energy. For satisfactory operation of heat engine there should be least 2 heat reservoirs source and sink.
Consider the robotic manipulator of Fig. 1, with a Revolute and a Prismatic Joint. Figure 1, shows the side view of the manipulator while figure 2. shows the top view of the manipu

A steel pipe with 50 mm OD is covered with a 6.4 mm asbestos insulation followed by a 25 mm layer of fiber-glass insulation [K = 0.0485 Wmk]. The pipe temperature is 393 K and the
Kinematics Equations Kinematics deals with problems involving distance, velocity, time and constant acceleration. The restraint that acceleration is a constant for these problem
Creating 3-d solid models Two basic approaches to create solid models are : (i) Constructive solid geometry (CSG or c-rep), and (ii) Boundary representation (b-rep).
