In the mechanical design process the first step is to ________. In which of the following refrigeration system, waste heat can be effectively used? In an interchangeable assembly, shafts of size 25.000 -0.0100⁺⁰∙⁰⁴⁰ mm mate with holes of size 25.000 -0.010⁺⁰∙⁰²⁰ mm. The maximum possible clearance in the assembly will be If 'P' is the force acting on the body, 'm' is the mass of the body and 'a' is the acceleration of the body, then according to Newton's second law of motion, The absolute pressure of air at the outlet of a compressor is called
