PIPSTEK -Properties of Irregular Planar Solids (Tektronix).

摘要

PIPSTEK is an Interactive Computer Graphics program for the calculation of the Properties of Irregular Planar Solids. This program utilizes the graphics terminal to determine the mass,weight,center of gravity,mass moments of inertia,products of inertia,principal axes and center of percussion of assemblies of irregularly shaped parts (not necessarily touching nor in the same plane) with respect to an arbitarily selected 3-axis coordinate system. The solids may either be described and read in on punched cards,or drawn at the graphics screen,or generated by attaching (and modifying) an existing file of parts. The inputted solids may be accumulated with other solids and their combined properties calculated. PIPSTEK was written for the CDC 6500/TEK 4014facility operating under Scope 3.4.2employing 15overlays and 56K octal of 60bit words of storage. (Author)
