计算图题 3-2(4)所示结构的内力时,应先计算[input=type:blank,size:4][/input]部分,后计算[input=type:blank,size:4][/input]部分。[img=301x195]179c2643580423c.png[/img]
举一反三
- 结构计算简图的简化原则是:[input=type:blank,size:4][/input],[input=type:blank,size:4][/input]主要简化内容为:[input=type:blank,size:4][/input],[input=type:blank,size:4][/input],[input=type:blank,size:4][/input],[input=type:blank,size:4][/input],[input=type:blank,size:4][/input]和[input=type:blank,size:4][/input]
- Watch Video 2 again, and make notes of the key supporting details for each main point.[img=1078x526]177ec0cc0dba55a.png[/img]1、[input=type:blank,size:4][/input]2、[input=type:blank,size:4][/input]3、[input=type:blank,size:4][/input]4、[input=type:blank,size:4][/input]5、[input=type:blank,size:4][/input]6、[input=type:blank,size:4][/input]7、[input=type:blank,size:4][/input]8、[input=type:blank,size:4][/input]9、[input=type:blank,size:4][/input]10、[input=type:blank,size:4][/input]
- 图题 3-2(7) 所示结构中,[tex=2.857x1.0]yIVMj0iMJ3CRpMGZqISVEQ==[/tex] 则[tex=2.857x1.214]Xg0xb/zomzZU1Pxkp2VV2A==[/tex][input=type:blank,size:4][/input],[input=type:blank,size:4][/input]侧受拉; [tex=2.857x1.214]AvHUaXJ2wHHdFB4dRK5+2w==[/tex][input=type:blank,size:4][/input],[input=type:blank,size:4][/input]侧受拉。[img=316x188]179c26bc7b822d3.png[/img]
- Watch Video 3 to find out details of the project ‘Green Horizon’. Fill in the following blanks.[img=479x132]177c8b86bc5690d.png[/img]1) .[input=type:blank,size:4][/input]2) .[input=type:blank,size:4][/input]3) .[input=type:blank,size:4][/input]4) .[input=type:blank,size:4][/input]5) .[input=type:blank,size:4][/input]6) .[input=type:blank,size:4][/input]
- 下图所示的结构,可以看做[input=type:blank,size:4][/input]结构,[input=type:blank,size:4][/input]结构,[input=type:blank,size:4][/input]结构。最准确地讲应该是[input=type:blank,size:4][/input]结构。[img=476x229]17a2935d5ad0de5.png[/img]
