求翻译：For two materials of equal area under the same lo ad,the one with the higher elastic modulus of 30 million pounds per square inch,or 2100000kiolgrams per square centimeter is 3 times as stiff as aluminun,10 tines as stiff as concrete,and 15 times as stiff as wood是什么意思？ 待解决

对两种材料领域的平等在同一罗特”的一个高弹性模量的每平方吋30磅,或每平方公分 2100000 kiolgrams是3倍,硬作为aluminun,10叉作为僵硬的混凝土和15倍的硬木材

为相等的区域二材料在同一个lo广告之下，那个与30百万磅每平方英寸的更高的弹性模数或者2100000kiolgrams每平方厘米是3倍僵硬象aluminun、10个尖叉一样僵硬象混凝土和15倍僵硬象木头
