Final answer:
Wave-particle duality does not apply to macroscopic objects, which is false, while the existence of constructive and destructive interference is true. Maximum shear stress in a T-beam can be calculated using the shear modulus, force, and the beam's geometry.
Step-by-step explanation:
The statement "wave-particle duality exists for objects on the macroscopic scale" is false. Wave-particle duality is a concept in quantum mechanics that describes how subatomic particles can exhibit both wave-like and particle-like properties. However, this duality is not observed on the macroscopic scale, where classical physics predominates.
The statement "The two types of interference are constructive and destructive interferences" is true. Constructive interference occurs when two or more waves combine to produce a wave of larger amplitude, while destructive interference occurs when two or more waves combine to produce a wave of reduced amplitude.
To determine the maximum shear stress in a T-beam at the section where the internal shear is maximum, one must consider factors like the geometry of the beam and the material properties, such as the shear modulus (S). Shear stress is evaluated by applying a force (F) perpendicular to the initial length (Lo) and parallel to the cross-sectional area (A).
