LMEC-4 Cov Khoom Siv ntawm Shear Modulus thiab Rotational Moment of Inertia

Kev Piav Qhia Luv:

Qhov piv ntawm kev ntxhov siab sab hauv rau kev ntxhov siab hauv qhov txwv elastic yog ib qho tseem ceeb los ntsuas qhov deformation ntawm ib yam khoom nyob rau hauv kev ntxhov siab. Qhov piv ntawm kev ntxhov siab ib txwm muaj rau kev ntxhov siab linear hu ua Young's modulus; qhov piv ntawm kev ntxhov siab shear rau kev ntxhov siab shear hu ua shear elastic modulus, lossis shear modulus luv luv. Young's modulus thiab shear modulus yog siv dav hauv kev tsim qauv engineering thiab kev xaiv cov khoom siv kho tshuab hauv tshuab, kev tsim kho, kev thauj mus los, kev kho mob, kev sib txuas lus thiab lwm yam kev lag luam.
