The rigid body of mass m shown in figure Q3 on page 4 has a circular base radius 4. Any section parallel to the yz plane is an equilateral triangle. Employ the triangular elements shown in figure Q4 to determine the volu V of the body by integration 3.1 Using the same elements as in 3.1, determine the mass moment of inertia the body about the x-axis in terms of m. Hint : the polar mass moment inertia of a triangular plate with mass m and equal sides of length 2b about axis x that passes through the center of a side is: 3.2 Zmb
