You are designing a beam that will serve as a load-bearing support for a roof. The beam is rectangular, with a width of 12 inches and a height of 16 inches. Calculate the moment of inertia, and discuss its importance in your design.
💡 Hint: Use the formula and remember to substitute the units correctly.
Given a T-section made of a rectangle and a smaller rectangle placed at its side, calculate its centroid. The base is 10 cm wide and 20 cm tall, and the smaller rectangle is 4 cm wide and 10 cm tall on top, centered across the base.
💡 Hint: Break down the triangle into two shapes to simplify calculations.
