This paper intends to expound some important definitions and conclusions in real variable function by using algebraicoperation, thus making a new approach to the use of computers in this field.
Based on energy theory, a simple critical force calculation for pressed beam with variable cross sections is derived. It reduces the complex integration algorithm into a simple algebraicoperation.
