Deflection of Beams is the measurement of structural deformity in a beam under any load. The deformity can be measured in terms of angle, distance, etc. Standard mathematical engineering formulas are used to calculate the beam deflection. Deflection of Beams questions are asked in the Applied Mechanics & Design (subject-specific section) section of the GATE ME exam.

GATE ME applicants will also face questions from the Deflection of Beams. It has applications in construction, structural analysis, etc. Read on to know more about the Deflection of Beams syllabus for GATE.

Important Deflection of Beams Topics for GATE ME

Topic	Explanation
Slope of Beam	The slope of a beam is defined as the angle between the shifted beam and the original beam position. Maximum deflection in a beam occurs when the slope is zero.
Mohr’s Method	Mohr’s Method is used to determine the slope & deflection of a beam using the moment diagram. The two theorems stated under Mohr’s Method are: • A tangent of the deflection curve is made in the moment diagram. The angle between the two points of the tangent is equal to the negative area of the whole moment diagram between the two points. Formula - BA=1EIArea AB BA is the angle between the two points (A &B) of the tangent and EI is the beam’s flexural rigidity. • The deviation of point ‘B’ from the tangent at point ‘A’ (EIdBA) is defined as the negative first moment w.r.t. to B. Formula – EIdBA=BAAmx , Am is the ‘first moment w.r.t. point ‘B’.
Method of Superposition	The load(s) contribution is added to find out the desired deflection of a beam in this method.
Simply Supported Beams	Beams that have only two supports i.e. pinned support and roller support, fall under Simply Supported Beams.
