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.

Question

. The hydraulic system of a backhoe is used to lift a load as
shown in Figure 11.45. (a) Calculate the force F the slave
cylinder must exert to support the 400-kg load and the 150-kg
brace and shovel. (b) What is the pressure in the hydraulic
fluid if the slave cylinder is 2.50 cm in diameter? (c) What
force would you have to exert on a lever with a mechanical
advantage of 5.00 acting on a master cylinder 0.800 cm in
diameter to create this pressure?
