根据马斯洛的需求层次理论,大多数大学生处于哪一层次的需求?
the method of sections is used to determine the ( ) acting on the surface of the sectioned body. in general, these resultants consist of a ( ), ( ), ( ), and bending moment.
伺服系统包括()和执行机构两大部分。
linear distributed loadings produce a ( ) having a magnitude equal to the ( ), and having a location that passes through the ( ).
the state of strain at a point is characterized by ( ) strain components: ( ) normal strains and ( ) shear strains. these components depend upon the original ( ) of the line segments and their ( ) in the body.
the deflection of the end a of the cantilevered beam is ( ). e = 200 gpa and i = 70.0(10^6) mm4.
when shear stress acts on a plane, then ( ) of a volume element of material at a point on the plane requires associated ( ) of the ( ) act on three adjacent sides of the element.
the maximum representing the maximum in-plane shear stress with the associated ( ) is oriented ( ) from the element representing the principal stresses.
the bending stress developed at corners a is ( ).
