Name Student Number 0 Given that the dimensions of each flan

Name: Student Number: 0 Given that the dimensions of each flange (striped) and the dimensions of each web (solid) is the same for all the shapes in Figure 4; which shape has the highest moment of inertia about the X-axis [2 Marks] X-axis Shape A Shape B -X-axis Shape C Shape D Figure 4 (i) Shape A (ii) Shape B (ii) Shape C (iv) Shape D (v) All have the same moment of inertia about the X-axis

Solution

Ans. Shape A.

moment of inertia depends on two factors 1) body\'s mass distribution and 2) axis we have choosen,with larger moments requiring more torque to change the body\'s rotation
