Determine the moment of inertia for the beam’s cross-sectional area about the *y* axis.

Community Answer

Step 1The given figure can be divided into three parts as shown below.Step 2The moment of inertia of beam is required about y –axis and the figure is symmetrical about y ’axis. So the moment of inertia about y-axis can be determined by using parallel axis theorem.The parallel axis theorem is given by,I_(y)=I_(y^('))+Ad_(x)^(2)Here, is moment of inetia about y-axis is moment of inetia about y^(')-axis A is the area of section d is th ...
