由“三个和尚没水喝”引出的力学问题思考

Reflection on the Mechanical Problems Led from“Three Boys no Boy”

三人抬水其中蕴含着力学原理,如何实现大家协调统一是力学知识在超静定问题中的应用.文章首先通过合理的抽象、假设,将此问题简化为力学模型;再经过分析、比较、计算,提出了解决方案,得出满意结果;最后又比较了三人抬水与三人抬木头的异同,增加了力学课程的趣味性,激发了学生学习的积极性,提高了学生的学习效率,对力学课程的教学改革有重要的启发作用.

Three boys carrying water contains the principles of mechanics.How to achieve harmonization is the application of mechanical knowledge to the statically indeterminate problems.Using rational abstractions and assumptions,the problem is firstly simplified to a mechanical model.Through the analytical and comparative calculations it then proposes solutions to the problem and obtains satisfactory results.Finally three boys carrying water and lifting wood are compared.Such approaches increase the mechanics course interesting,stimulate students' enthusiasm,improve students' learning efficiency,and enlighten the teaching reform of mechanics course.
