| A set of mechanical engineering programs to calculate the cross section area of a cylinder, the maximum bending moment on a cylinder at yield, the collapse pressure on a 75/80/110 KSI yield pipe, von Misses stress, yield pressure, shear area and bearing area on acme threads, gross margin when cost and price are known, price when cost and gross margin are known, and future value when present value, interest per year, and period in year are known. |
