材料力学中的弯曲正应力、弯曲变形、主应力三个实验一般是集中在一个很短的时区里进行,并且都要在万能试验机上完成.如果在同一学期开设材力课的班次多,安排实验室就会发生困难.解决这一矛盾的办法之一可以在实验教学装置上想办法.下面就介绍
Bending normal stress, bending deformation, and principal stress in material mechanics are generally concentrated in a short time zone and must be completed on a universal testing machine. Lab will be difficult to solve one of the ways this contradiction can be in the experimental teaching device to find a solution.
