Machinery's Handbook 31st Edition & 4090 Sheet Metal / HVAC Pro Calc Calculator (Set): Large Print

Since the first edition published more than 100 years ago, Machinery's Handbook has been the most popular engineering resource of all time. Universally considered the principal reference in the manufacturing and mechanical industries, the Handbook is the ultimate collection of essential information needed by engineers, designers, drafters, metalworkers, toolmakers, machinists, educators, students, and serious home hobbyists. From engineering and design departments, machine and metalworking shops, and a wide range of manufacturing and industrial facilities, to countless classrooms and workshops worldwide, this is the must-have technical reference.

The Sheet Metal/HVAC Pro Calc is a versatile calculator that enables tradesmen to calculate complex problems with dedicated key functions that are labeled in standard industry terms. The calculator has other advanced built-in construction-math functions to enable HVAC and sheet metal tradesmen to do their work alongside other trades. In addition to the built-in functions, this calculator can handle order of operation, perform square, cube, square root, and cube root calculations, determine ArcK constant for convenient Arc length solutions, and has an offset functions for "S-shaped" bends in ductwork. It can also help solve the layout for wrapper length, centerline radius, and the angle. It works as a regular calculator with typical symbols.

Together, the Machinery's Handbook and Sheet Metal/HVAC Pro Calculator are the perfect combination resource, providing instant access to metrics and measurements with the flip of a page and press of a button. This incredible set is a must-have for students and professionals in the sheet metal and HVAC fields.
