(above) Students in aeronautical engineering have a chance to study the flight characteristics of aircraft as they observe scale models tested under simulated flight conditions in the department wind tunnel. above) Technically it is called a hyperbolic paraboloid but almost every member of the student body had at least one other time for it. The structure was built as an experiment in construction and design. Photos by Dick Roberts Tom Sieafried. Editor (right) Machine tools, their care, use, and handling are taken up in still another segment of shop practice. Potential engineers gain practical experience in the operation of such equipment as turret lathes and mills. (extreme right) The techniques and theory of welding and cutting are presented in the welding division of the shop practice course n (below) Shop practice is a general survey course in the practical elements of industrial processes. Pictured here are students with their instructor demonstrating a step in procedure during that part of the course which deals with the foundry.
