Why is the depth of a Beam always greater than its width? | Why Beams have more Depth than Width?

In this video, I have discussed, Why is the depth of a Beam always greater than its width? When a load is applied on a beam, it tends to deflect the beam & generates some bending moment within the beam. The primary role of a beam is to withstand the moment generated by the load applied to it. As the beam opposes deflection, it generates a substantial moment, which it must endure. 2nd channel @CivilTutorHindi Complete Building Design combo course (Hindi + English) https://fnrjb.courses.store/130675 Site Engineer Course in English https://fnrjb.courses.store/137112 Site Engineer Course in Hindi https://fnrjb.courses.store/215740 Quantity Surveying Course in Hindi https://fnrjb.courses.store/52692 Advanced Quantity Surveying + Bar Bending Schedule (Hindi / English) https://fnrjb.courses.store/264604
