Building a Popsicle-Stick Bridge The goal: to build the strongest possible bridge to take a matchbox car‚ using wooden popsicle sticks. Constraints: The bridge must span a 55cm gap No more than 100 popsicle sticks may be used The sticks may not be cut Only white glue may be used Construction paper may be used for the deck only The test load is applied to a 4cm-wide section at the top of the arch. The test jig looks like this: (Well-built bridges can

wire size should be commercially available and that the stress at the solid length be no longer greater than the torsional yield strength. Further functioning of the spring should be stable. Stability of the spring (Buckling) Buckling of column is a familiar phenomenon. Buckling of column is a familiar phenomenon. We have noted earlier that a slender member or column subjected to compressive loading will buckle when the load exceeds a critical value. Similarly compression coil springs will buckle

INTRODUCTION Attention-arousing material: Do you know that every hour someone dies in crash simply from not buckling his or her seat belt and you can be a victim if you don’t simple buckle it when you get in your car? Thesis-statement: Today I will try to persuade you that the first thing you have to do after sitting in your car is buckling your seat belt. Credibility Statement: While investigating for this speech I confirmed that using a seat belt do save lives and also prevent you of serious

Do you know how many people die in a car accident each year? 40‚000 people die every single year. Did you know that a simple task of just buckling up can reduce that up to 50%? Imagine 20‚000 people saved with by the simple click of a seatbelt. A thirty mile-per-hour car crash for an unbelted child is the same as them jumping out of a third story window. Broken bone‚ dislocations‚ bruises‚ brain and head injuries are dangerous and are very common in cars accidents. Everyone should always wear a

The design and modeling of microscale electro-mechanical systems (MEMS) is a unique engineering discipline. At small length scales‚ the design of resonators‚ gyroscopes‚ accelerometers‚ and actuators must consider the effects of several physical phenomena. MEMS devices and sensors may even utilize multiphysics phenomena for its very function or for increased sensitivity. To this end‚ the MEMS Module provides user interfaces for electromagnetic-structure‚ thermal-structure‚ or fluid-structure interactions

The engineers depended on computer analysis to assess the safety of their design. The roof design was extremely susceptible to buckling a mode of failure not considered by the computer analysis and‚ therefore‚ left unaccounted for (Shepherd and Frost‚ 1995). Due to the construction manager’s refusal to hire a structural engineer for the purpose of inspection‚ no one realized the

Did you know that the cost of hospital care for unbelted drivers is 50% higher than the cost for a belted driver? Studies by the National Highway Traffic Safety Administration also show that most unbelted drivers tend to drive more
