would find that there would be too many “unknowns” and we would not be able to complete the calculations. 3.2 Instead we will use a method know as the the flexibility method‚ which uses an idea know as strain energy. 3.3 The mathe‚atical approach to the flexibility method will be found in the most appropriate text books. Basically the flexibility method uses the idea that energy stored in the frame would be the same for a given loa for a given weather load wheather or not the redundant member wether

Grease is a 1950’s set performance that was re interpreted into a show at North Lincoln High School on March 18th‚ 2017. Presently directed by Aubrey Bridges and Stage managed by Emily Walker‚ it stuck to the original scenes of the play and executed them brilliantly. This show contributed to the on-the-go energetic lifestyle that teenagers still have today‚ intermixing the 50’s issues that high schoolers still experience today. Starting the show off with the rock and roll music‚ Grease is a fun musical

uses computer graphics and software to enable engineers to do most of design activities needed to complete engineering design that include creating parts in 3D‚ assembling them‚ and producing engineering drawings. CAM generates tool path (i.e.‚ NC [numerical control] part program) with reference to CAD database for geometric references. This CAD/CAM technology is a result of advancement of computer hardware and software technologies and used in almost all areas of industries in many different forms helping

Disadvantages Advantages CNC machines are more expensive than manually operated machines‚ although costs are slowly coming down. CNC machines can be used continuously 24 hours a day‚ 365 days a year and only need to be switched off for occasional maintenance. The CNC machine operator only needs basic training and skills‚ enough to supervise several machines. In years gone by‚ engineers needed years of training to operate centre lathes‚ milling machines and other manually operated machines. This

ABSTRACT This paper describes numerical simulation of a selected soft missile impact small scale test. The main aim of the testing program is to provide data for the calibration and verification of the numerical simulation models for soft missile impact time-history simulation. The experiments are conducted both with dry and fluid filled missiles. The objective of the tests with fluid filled missiles is to investigate the release speed and the droplet size of the fluid spray release in the impact

Chapter 7 Ordinary Differential Equations Matlab has several different functions for the numerical solution of ordinary differential equations. This chapter describes the simplest of these functions and then compares all of the functions for efficiency‚ accuracy‚ and special features. Stiffness is a subtle concept that plays an important role in these comparisons. 7.1 Integrating Differential Equations The initial value problem for an ordinary differential equation involves finding a function
