Introduction The Bending Stress in a Beam experiment introduced students to stress and strain‚ bending moment‚ section properties and the bending equation. 2. Theory Considering the simply supported beam as shown in Figure 1‚ there are two point loads ( W / 2 ) applying to this beam. Figure 1 Beam set-up and schematic The applied bending moment (M) is calculated as: M = where: M=Bending moment (Nm) L=Span length as shown in Figure 1 (m) From the bending equation‚ we have: WL 2 (1) M

as I lay alone in my bed at night. It had never felt real until now. I stared at it as it hung there‚ as it hung unaware of the meaning it gave to me at this moment. Those few seconds stretched for hours‚ stretched to encompass the span of a lifetime in the flash of a blinking eye. And that’s what it all now felt like; a blink‚ a moment‚ a flash. Is that what it will feel like at the end? A flash? When I was a little girl‚ my father took me to the fair. He bought me a

It is found that the deflection of the beam changes linearly with the load and as the beam

well‚ but I consider this to be a better example. Integrated Mechanical Testing Laboratory BUCKLING OF A COLUMN Objective The primary purpose of this experiment is to verify the critical load for buckling‚ relationship among the bending-moment and deflections‚ for different end conditions when a rectangular beam is subjected to axial loading. Theory A column is a member subjected to axial compressive forces. When a column is concentrically loaded‚ it is expected to reach its yield

as well as the stresses and strains developed as a result. Objective “To study the stress and strain induced in an I-beam under symmetric and unsymmetrical bending” [2]. Theory: σ – Normal stress (Mpa) ε – Strain (mm/mm) M – Moment (kN∙m) I – Moment of inertia (mm^6) E – Modulus of elasticity (Mpa) G – Modulus of elasticity (Mpa) v – Poisson’s ratio. L – Length (m) *Subscripts x‚ y‚ z indicate plane of reference. The strain rosettes are orientated so that θb = 0‚ θc = -45
