Answer #1

correct answer is Neutral Surface.

Because this is this surface at which bending stress is zero and strain is zero so that it will not bend and every element on this surface is remains on it's surface before bending and after bending. This sirface is known as Neutral Surface.

False option neutral axis -Neutral axis is the axis passing from neutral surrface is known as neutral axis

flat surface is a suface which is flat

Longitudial surface - along which beam or column or any structure is kept , is termed as longitudinal axis.

comment for any doubt about this solution thank you

Dr. Ben Blalock has hired us to determine the length of the power lines between two towers, and the tension in the power line. We do this by sending a longitudinal pulse and then a transverse pulse down the line. It takes 0.15 sec for the longitudinal pulse to return, and 1.4 sec for the transverse pulse to return. The power lines are made of 1.9 inch diameter aluminum wire, with E=10.8x106 psi and weighing 175 lb/ft3. A. What is...

In the case of a uniform electric field and a flat surface, the electric flux is defined as the dot product of the electric field and the area, where the direction of the area is the normal to the area pointing out of a closed region. Consider a cube that measures 4.0 m on edge. The edges lie along the coordinate axes x, y, and z, with one corner at the origin, and the other corners having positive coordinates. A...
