Overview of Exhibits
The exhibition items consist of a mechanical booth with two layers of nail steel plates embedded inside. The nails of the two steel plates are arranged in a staggered manner, with the upper steel plate having a single row of nails and a double row of holes, while the lower steel plate is opposite. Participants can lie on the booth, and after turning on the power, the upper steel plate nails built into the booth will slowly rise and extend from the holes on the table, slowly lifting the participants up (the nails are relatively sparse). Participants can click the start button again, source factory of science museum exhibits - Shanghai Inertia Automation Co., Ltd. Remind everyone to slowly raise the nails on the lower steel plate, pass through the double row holes on the upper steel plate, and then extend from the holes on the table. At this time, the two layers of steel plate nails overlap and interlock (the nails are denser), but the nails will not pierce the participant's body. Click the reset button next to it to retract and restore the steel plate to its original state. source factory of science museum exhibits - Shanghai Inertia Automation Co., Ltd. Participants are reminded that they can control the lifting of the steel plate and change the density of nails through two buttons, experiencing the difference between the two.
Science Behind It
pressure
The ratio of the pressure exerted on an object to the area under force is called pressure, which is used to compare the effects of pressure. The greater the pressure, the more pronounced the effect of pressure. The formula for calculating pressure is: p=F/S, the unit of pressure is Pascal, and the symbol is Pa. source factory of science museum exhibits - Shanghai Inertia Automation Co., Ltd. Reminder: In a nail bed, with more nails, the area under stress increases, and the pressure assigned to each nail decreases. On the surface, it appears that the force has been decomposed, but in reality, the force has not changed. What has changed is the pressure applied to each nail.
