Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.

Consider the slender rod of length L and mass m that rotates around the point O' in the vertical plane. Its center of mass is at point G. The rod is at rest and forms an angle of 0 with the horizon- tal when a winch is activated to raise the rod. At this instant, the tension (of magnitude T) in the horizontal rope joining the winch to point A causes an angular acceleration, a = Ö. Consider the weight of the rod and assume that the reaction force at point O' is of the form R = Rxî1 + Ryî2. Solve for the tension in the rope and the reaction force components, (T, Rx, Ry). (Hint: Apply E1L for the translation of the center of mass and E2L for the fixed-axis rotation. Make sure you consider the inertia of the slender rod about the rotation point O' not G).

The wheel D is attached by a light member AB to a slider C having a mass of 30 kg. If the system is at rest at the instant shown, what is the acceleration of slider C?

A spring of rest length La (no tension) is connected to a support at oneend and has a mass M attached at the other. Neglect the mass of the spring, the dimension of the mass M, and assume that the motion is confined to a vertical plane. Also, assume that the spring only stretches without bending but it can swing in the plane. (a) Using the angular displacement of the mass from the vertical and thelength that the string has stretched from its rest length (hanging with themass m), find Lagrange’s equations. (b) Solve these equations for small stretching and angular displacements.
