Total questions: 10
Worksheet time: 5mins
On bending of a beam, which is the layer which is neither elongated nor shortened?
Axis of load
Neutral axis
Center of gravity
Moment of inertia
The bending stress is ____________
Directly proportional to the distance of layer from the neutral layer
Inversely proportional to the distance of layer from the neutral layer
Directly proportional to the neutral layer
Does not depend on the distance of layer from the neutral layer
What is the expression of the bending equation?
M/I = σ/y = E/R
M/R = σ/y = E/I
M/y = σ/R = E/I
M/I = σ/R = E/y
