图所示受力结构中,若杆1和杆2的拉压刚度EA相同,则节点A的水平位移http://edu-image.nosdn.127.net/_PhotoUploadUtils_fedadeef-f4b1-4edc-b43e-20dbcf3eaa71.png ( )。 http://edu-image.nosdn.127.net/983F5B18FD81AB44B8E941A30436388F.png?imageView&thumbnail=890x0&quality=100
举一反三
- 结构如图,载荷F可在横梁(刚性杆)DE上自由移动。杆1和杆2的横截面积均为A,许用应力均为http://edu-image.nosdn.127.net/_PhotoUploadUtils_0ba163eb-b119-4401-b3dc-241ce10b3a04.png(拉、压相同)。求载荷F的最大许可值。 http://edu-image.nosdn.127.net/7F1837B1378E9A01E7FCE29BB60DE9B3.png?imageView&thumbnail=890x0&quality=100
