Cross Sectional Area Of A Rod

For example the cross section of a cylinder when sliced parallel to its base is a circle.

Cross sectional area of a rod. Assuming the rod has a circular cross section with radius r the cross sectional area is pi r 2 the units being square inches if the radius is in inches and so on. Calculate the cross sectional area of rod 1 and the normal stress in the rod. The cross sectional area is the area of a two dimensional shape that is obtained when a three dimensional object such as a cylinder is sliced perpendicular to some specified axis at a point.

The cross sectional area is a π r 2 π d 2 2 π 4 d 2 a π 4 15 mm 2 225π 4 mm 2 the area is approximately 176 71 mm 2. A metallic rod of length l and cross sectional area a is made of a material of young s modulus y. Determine the cross sectional area for the pin at b and the average shear stress in the pin.
