Hello<br />My class activity is <br />To determine how the shape of a material can<br />make it stronger.<br /><br /><br /><br />Metarials : <br />Papers , Glue<br /><br /><span style="color: #333333"><span style="font-family: Raleway, Helvetica, Arial, Lucida, sans-serif"><span style="font-size: 14px;">We are going to test the strength of paper, folded in differently  shaped columns, by piling books on top. This is very similar to how columns are used to support buildings and other structures.<br /><br /></span></span></span><span style="color: #333333"><span style="font-family: Raleway, Helvetica, Arial, Lucida, sans-serif"><span style="font-size: 14px;">The cylinder can support the most books because it’s walls don’t have any edges. The force of the books cannot become concentrated in a particular area. The load is distributed evenly. In other words, all parts of the cylinder are sharing the load of the books.  All parts of the cylinder, therefore, contribute to it’s overall strength until, finally, it collapses.</span></span></span><span style="color: #333333"><span style="font-family: Raleway, Helvetica, Arial, Lucida, sans-serif"><span style="font-size: 14px;">The square and triangle deform more easily.  They shift the weight of the books to their edges and corners, which deforms their walls and leads to a quick collapse.  They are unable to carry weight only at their edges.  </span></span></span><span style="color: #333333"><span style="font-family: Raleway, Helvetica, Arial, Lucida, sans-serif"><span style="font-size: 14px;"><br /><br /></span></span></span><br /><br />
