Question

A Review Learning Goal: To be able to calculate the moment of inertia of composite areas An object's moment of inertia is calculated analytically via integration, which involves dividing the object's area into Figure < 1 of 1 Part A - Moment of inertia of a triangle with respect to the x axis A composite area consisting of the rectangle, semicircle, and a triangular cutout is shown (Figure 1). Calculate the moment of inertia of the triangle with respect to the x axis. The dimensions are m = 70.0 mm and n = 35.0 mm. Express your answer to three significant figures and include the appropriate units. View Available Hint(s) MA ? 11X- 24400000 mm Submit Previous Answers * Incorrect; Try Again; 4 attempts remaining
